HALIFAX -- An RCMP staff sergeant is facing several charges including drug trafficking following an 11-month investigation involving Mounties from five provinces.

Nova Scotia's Serious Incident Response Team says Craig Robert Burnett has been charged with theft of cocaine, trafficking cocaine, breach of trust and laundering proceeds of crime.

Burnett is an RCMP member with the operational communications centre in Truro.

A news release says an investigation was launched last September after RCMP received information that in 2011, 10 kilograms of cocaine was stolen from an exhibit locker and replaced with another substance.

The team says early on in the investigation, it was determined that significant resources were required and Mounties from Nova Scotia, British Columbia, Alberta, Prince Edward Island and Newfoundland and Labrador were brought in to assist.

Burnett was scheduled to appear in Halifax provincial court on Thursday.
