Two former officers from Certis CISCO were each sentenced to one week in jail on Friday, July 17, 2026, after pleading guilty to obstructing justice related to a Corrupt Practices Investigation Bureau (CPIB) inquiry into e-vaporisers and contraband cigarettes.

Tan Wee Keong, 38, an assistant enforcement supervisor with Certis CISCO Auxiliary Police Force assigned to the Health Sciences Authority's Tobacco Regulation Branch (TRB) at the time, disclosed details of the CPIB investigation to his former colleague, Reggie Choo Beng Kwang, 33. Choo, who had resigned from the Tobacco Regulation Branch before May 2022, subsequently discarded at least one e-vaporiser and three packs of e-vaporiser pods that could have served as evidence.

Court documents reveal that around May 2022, Tan learned that Choo used e-vaporisers and advised him not to continue due to health concerns, also warning that Choo's name had surfaced during the CPIB interview. Choo faced an additional charge for deleting a WhatsApp conversation with Tan, which was considered during sentencing.

The CPIB stated that the accused knew they were not to discuss investigation details, both as law enforcement officers and due to direct instructions from CPIB. Defense counsel noted the minimal impact of their actions and that being law enforcement officers did not automatically warrant jail time.

This case highlights the legal consequences of interfering with investigations, even among former colleagues in enforcement roles.
