An Office of the Police Complaint Commissioner investigation into the actions of suspended Victoria Police chief Frank Elsner has been extended for the fourth time.

The police complaint commissioner launched several investigations into Elsner's behaviour after an internal police investigation revealed Elsner had engaged in an inappropriate relationship with the wife of a subordinate officer. He's also being investigated for allegations he tried to influence the internal investigation; and for the alleged harassment of several female employees.

In a notice of extension, police complaint commissioner Stan Lowe says he's satisfied the investigative team led by BC RCMP Chief Superintendent Sean Bourrie has worked diligently and their request for an extension is reasonable in light of the number of investigative tasks being taken.

The completed investigation is now due by February 24. Elsner remains suspended, with pay, pending the results.
