Summary
Public Prosecutor v Lokman bin Abdul Rahman and another ([2020] SGHC 48) is a High Court decision concerning two brothers charged under the Misuse of Drugs Act (MDA) in connection with diamorphine (heroin). The first accused, Lokman, was charged with trafficking by possession for the purpose of trafficking, while the second accused, Mohamed Mubin bin Abdul Rahman, faced a charge of abetment by instigation of Lokman’s trafficking. Both men claimed trial and advanced competing narratives about who was the “real” drug trafficker and what role the other brother played.
The court accepted Lokman’s account that he acted as a courier assisting Mubin’s trafficking activities. It rejected Mubin’s denial and his attempt to portray himself as a mere consumer with no knowledge of the drugs found in Lokman’s possession or at the relevant premises. On conviction of amended charges, Lokman received life imprisonment, and Mubin received the mandatory death sentence for the trafficking offence, reflecting the statutory sentencing framework for Class A controlled drugs.
What Were the Facts of This Case?
The events giving rise to the charges occurred against a background of drug storage and communications between the brothers. On 8 September 2015 at about 10.30pm, Central Narcotics Bureau (CNB) officers arrested Lokman at the ground floor lift lobby of Katong Park Towers (“KPT”), 114A Arthur Road, Singapore. At the time of arrest, Lokman was carrying a black bag containing two bundles of diamorphine, later marked A1E1A and A1F1A. The diamorphine content in each bundle was not less than 19.88g and 19.40g respectively. The drug analysis and chain of custody were not disputed, which narrowed the dispute to issues of knowledge and purpose of possession.
Beyond the two bundles forming the core of the trafficking charge, additional drugs were found in Lokman’s possession. In the black bag, besides A1E1A and A1F1A, CNB recovered five packets of diamorphine and 50 tablets of ethylone and methoxetamine. A further green and black bag carried by Lokman yielded five packets of diamorphine and three packets of methamphetamine. These additional items were relevant to the overall context of the brothers’ activities, even though the charges were framed around the specific bundles and quantities.
After arrest, Lokman was taken to the KPT Unit at #08-06 South Tower at KPT, where he was residing. A search of the unit produced further evidence. From the bedroom of the centre sub-unit, CNB recovered one packet and one straw of diamorphine, one packet of methamphetamine, and a roll of black tape. From the living room of the same sub-unit, CNB recovered six packets of diamorphine, three rolls of black tape, and a clear plastic wrapped with black tape. The presence of diamorphine and packaging materials supported the inference that the premises were used for drug-related activities, including packing and storage.
CNB also recorded communications made by Lokman using his mobile phone after his arrest. Under CNB supervision, Lokman communicated with a person identified as “Edy” and with Mubin. The recordings were later transcribed and translated. These communications were central to the prosecution’s theory that Mubin was directing Lokman’s actions, including delivery arrangements. The tenancy documents further indicated that the KPT Unit was rented to Mubin and one Siti Rohani binte Mohamed Ali, with monthly rental paid by Mubin. The girlfriend of Mubin, Tihani binte Ibrahim, had used Siti Rohani’s identity card to secure the lease. On the night of Lokman’s arrest, Tihani and her infant son were at the KPT Unit.
Mubin was arrested later, on 5 October 2015 at about 5.40pm at M28 Minimart, Blk 182A Rivervale Crescent. At the time of his arrest, two packets of methamphetamine, three packets of diamorphine, empty sachets, and a weighing scale were found on him. This evidence was used to contextualise Mubin’s involvement in drug trafficking activities rather than a purely consumer role.
What Were the Key Legal Issues?
The first legal issue concerned Lokman’s liability under the trafficking provision in the MDA. For a charge under s 5(1)(a) read with s 5(2), the prosecution had to prove: (a) possession of the controlled drug; (b) knowledge of the nature of the controlled drug; and (c) that the possession was for the purpose of trafficking, which was not authorised. While possession and knowledge were effectively admitted by Lokman (he admitted possession of the bundles and knowledge that they contained diamorphine), the contested element was the purpose of possession—whether Lokman was acting as a courier for trafficking or whether there was some other explanation.
A second issue arose from the prosecution’s alternative reliance on statutory presumptions. The prosecution sought to establish, by presumption under s 17 of the MDA, that Lokman’s possession was for the purpose of trafficking. This required the court to consider how the presumption operates in the overall evidential framework and whether the defence evidence rebutted it on a balance of probabilities, as is typical in MDA cases involving presumptions.
For Mubin, the key issue was whether the prosecution proved abetment by instigation under s 12 of the MDA. Abetment by instigation requires proof of the actus reus of instigation—“active suggestion, support, stimulation or encouragement” of the primary offence—and the mens rea—intention that the person abetted perform the act abetted, together with knowledge of the circumstances constituting the offence. The court therefore had to assess whether Mubin gave instructions to Lokman to retrieve, pack, and deliver the diamorphine bundles, and whether Mubin had the requisite intention and knowledge.
How Did the Court Analyse the Issues?
The court’s analysis began with the statutory structure of the MDA offences. For Lokman, the elements of trafficking by possession for the purpose of trafficking were set out by reference to established authority, including Muhammad Ridzuan bin Md Ali v Public Prosecutor and other matters [2014] 3 SLR 721. The court emphasised that “traffic” includes selling, giving, administering, transporting, sending, delivering or distributing, and that trafficking is established where a person possesses the drug for the purpose of trafficking. In this case, the prosecution’s task was not to re-litigate the existence of the drugs or the chain of custody, but to prove the purpose behind Lokman’s possession.
Lokman’s defence was that he was a courier working for Mubin. He maintained throughout investigations and trial that he helped Mubin in exchange for accommodation, drugs, and money. This narrative was consistent with the prosecution’s theory that Lokman acted under Mubin’s instructions. Importantly, Lokman admitted possession of the two bundles and knowledge of their nature as diamorphine. The court therefore focused on whether Lokman’s explanation about his role as a courier was credible and whether it aligned with the surrounding facts, including the communications recorded after his arrest and the drug-related items found at the KPT Unit.
Lokman’s account of 8 September 2015 was detailed. He said that Mubin called him in the afternoon and instructed him to return to the Holland Close Flat. Lokman then received instructions to retrieve all drugs stored at the KPT Unit and bring them back to Holland Close. He was specifically instructed to retrieve two bundles of heroin (street name for diamorphine) and any other drugs remaining at the unit. Later in the evening, Lokman received another telephone call from Mubin instructing him to deliver one of the bundles to Edy. Lokman said he packed A1E1A and A1F1A into two separate bags and placed them into his black bag, which he was carrying when arrested.
In contrast, Mubin denied giving instructions to Lokman and denied knowledge of the drugs found on Lokman or within the KPT Unit. Mubin claimed he was a moderate consumer of “ice” and that Zaini supplied him only ice. He also argued that he was not living at the KPT Unit at the time of Lokman’s arrest and that he did not leave drugs there. Mubin’s narrative sought to explain his relationship to the premises through a timeline: he said he stayed at the KPT Unit only from around April to June 2015, moved to Soho Life at Joo Chiat thereafter, and only invited Lokman to move into the KPT Unit in mid-July 2015. He further said that in late July he moved into the Holland Close Flat, and that in August Tihani and her son moved into the KPT Unit. Mubin also alleged that Lokman falsely implicated him due to rivalry between the brothers over the affections of Mubin’s former wife, Hasina, and to escape the death penalty.
The court treated the central factual issue as one of credibility and inference: whether the evidence reflected Lokman as a courier acting under Mubin’s direction, or whether Mubin was an uninvolved consumer and Lokman had framed him. The court’s approach, as signalled in the opening paragraphs of the judgment, was to evaluate the totality of circumstances. It found that the facts reflected the former scenario—Lokman assisting Mubin—rather than the latter. This conclusion was consistent with the prosecution’s reliance on recorded communications and the broader context of drug storage and packaging materials at the KPT Unit.
For Mubin’s abetment by instigation charge, the court applied the established framework for instigation. It required proof of active suggestion, support, stimulation or encouragement, and the requisite intention and knowledge. The prosecution’s theory was that Mubin ran a drug trafficking business and that Lokman was assisting him as a courier. The court considered that Lokman’s narrative of receiving instructions from Mubin, coupled with the recorded communications and the presence of drug-related items at the KPT Unit, supported the inference that Mubin had directed the retrieval and delivery of the bundles. In other words, the court treated the instructions to retrieve, pack, and deliver the diamorphine as the “active suggestion” element of instigation, and it inferred the mens rea from the nature of the instructions and the surrounding evidence of Mubin’s involvement.
Although the extract provided does not reproduce the entire reasoning section, the court’s stated finding at the outset is clear: it accepted Lokman’s evidence and rejected Mubin’s denial. That finding would necessarily have been grounded in the court’s assessment of the internal consistency of Lokman’s account, its alignment with objective evidence (such as the drugs and packaging materials found at the KPT Unit), and the plausibility of Mubin’s alternative explanations. The court’s acceptance of Lokman’s account also meant that the statutory presumption under s 17 (where relied upon) would not have been rebutted in a manner sufficient to create reasonable doubt or to displace the inference of trafficking purpose.
What Was the Outcome?
After both accused were convicted on amended charges, the court imposed the statutory sentencing consequences. Lokman was sentenced to life imprisonment. Mubin, whose liability was established for the trafficking offence through the abetment by instigation framework (as reflected in the amended charges and conviction), was subjected to the mandatory death sentence.
Practically, the outcome underscores the court’s willingness to treat courier roles as integral to trafficking where the evidence shows possession for trafficking purposes and where the primary organiser’s instructions can be inferred from communications and surrounding circumstances.
Why Does This Case Matter?
This case is significant for practitioners because it illustrates how Singapore courts approach the evidential assessment in MDA cases where the dispute is not about the presence of drugs but about knowledge, purpose, and the attribution of roles within a trafficking operation. The court’s acceptance of a courier narrative—when supported by objective evidence and communications—demonstrates that “courier” is not a legal defence that automatically reduces liability. Instead, the legal question remains whether the accused possessed the drug for the purpose of trafficking and whether the prosecution proved the requisite mental elements.
For abetment by instigation, the decision is also a useful reference point. It shows that instigation can be established through evidence of instructions and direction, and that courts may infer the necessary intention and knowledge from the nature of the conduct and the context of the drug operation. Where recorded communications exist and align with the accused’s account, they can be decisive in proving the actus reus of instigation.
Finally, the case highlights the practical sentencing consequences under the MDA. Once the court is satisfied that the offence falls within the statutory framework for Class A controlled drugs and the relevant trafficking liability is made out, the mandatory death sentence may follow for the principal trafficking offender, while other participants may receive life imprisonment depending on how their liability is characterised on the amended charges.
