Four members of the Canadian military have been charged with drug-related offences following an investigation by the Force's National Investigation Service.

The military says Able Seaman Colin Beswick, who is based in Halifax on HMCS Montreal, was charged earlier this week with drug trafficking and possession, and possession of a prohibited weapon.

Master Cpl. Andrew Pollett, Able Seaman David Oldenhof and Ordinary Seaman Alexander DeMontmorency were charged with drug possession.

All are based at CFB Halifax. 

The case is being handled by the military justice system.
