The RCMP plans to hold disciplinary hearings for 12 Mounties on the 2010 Vancouver Olympic security team who were sent home for alleged misconduct.

During the 2010 Winter Games in February, authorities acknowledged some members of the 10,000-member security team were sent home, but few details of the incidents were released until Monday.

Police did reveal during the Games that a senior RCMP officer was charged with shoplifting.

The RCMP — the force in charge of all security officers at the Olympics — now says that of the 15 officers sent home early, 12 were with the RCMP, one came from the Abbotsford, B.C., police, one from the Ontario Provincial Police and one from Peel regional police in Ontario.

Details of the alleged misconduct were not disclosed in all 15 cases, but four incidents involved inappropriate sexual advances or sexual touching. Those incidents occurred on the ships docked at Vancouver as housing for the security forces, police said.

The allegations of sexual misconduct suggest that police officers may have been the victims as well as the perpetrators.

Police didn't recommend any charges in connection with those allegations.

Five alleged cases of misconduct involved firearms, although no shots were ever fired. Guns were left behind in airports, washrooms and other places, and one officer showed up with his weapon but forgot to load it, the RCMP said.

There were also eight incidents of drunkenness among police officers, both on and off duty.

The term misconduct can refer to a number of violations, including skipping shifts, being drunk on the job or, as in the case of one senior officer, shoplifting at a retail store in Burnaby while off duty.

The security cost for the Games was estimated at about $1 billion.
