Pannir, 36, is set to be executed in Singapore on Wednesday for trafficking 51.84g of diamorphine through the Woodlands checkpoint in 2014.

Bukit Aman narcotics crime investigation department (NCID) director Hussein Omar Khan said efforts to obtain fresh evidence in his case, including visiting him at Changi prison in Singapore on Sept 27, did not generate any information that would allow further investigations to be carried out in Malaysia.

Hussein said his department’s investigation began after Singapore’s Central Narcotics Bureau (CNB) and Pannir’s family members informed him that Pannir had been tricked by a suspect into bringing drugs to the republic.

“NCID had identified the individual in question in 2022 and February 2025,” Hussein said in a statement.

“However, the investigation found that the information provided had no operational value and could not link the individual to the case involving Pannir.”

Hussein said Malaysian police respect the rule of law of other countries and adhere to the principle of non-interference.

“We understand the pain of the families and communities,” he said.

“However, Malaysians are reminded to always obey the laws of the country they are visiting, especially with regards to suspicious activities.”
