TORONTO -- A senior Ontario Provincial Police Association official has been dismissed.

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 confirmed through a union spokesman Sunday the OPPA board voted to dismiss chief administrative officer Karl Walsh, but the spokesman would not provide further details.

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, Ont., three vehicles registered in its name and a Toronto travel company. The production orders sought copies and backups of union email accounts belonging to its president Jim Christie, vice-president Martin Bain 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.
