OPP have suspended three officers named in an RCMP investigation.

In a news release issued late Sunday afternoon, OPP stated that Det. Sgt.  James Christie, Const. Martin Bain and Const. Karl Walsh have been suspended.

It follows an RCMP investigation that alleges the top leaders of the police force's union set up a sophisticated network of schemes involving secretly owned companies and offshore investments to defraud union members.

Acting union president Doug Lewis also confirmed through a union spokesperson on Sunday that the Ontario Provincial Police Association board voted to dismiss Walsh, the chief administrative officer.

The allegations against senior union officials and others are laid out in documents filed with the Ontario Superior Court to obtain search warrants and production orders for a March 6 raid on union offices and other locations.

Documents released Friday show that among the warrants' targets were the union's offices in Barrie, three vehicles registered in its name and a Toronto travel company. The production orders sought copies and backups of union email accounts belonging to Christie, the union president, Bain the vice-president and Walsh.

According to the union, Walsh had previously been placed on administrative leave, while Christie and Bain had taken voluntary leaves of absence.

None of the allegations have been proven and no charges have been laid. An RCMP spokesman said Friday the investigation is ongoing and declined to comment further.
