A Quebec provincial police officer has been fired after pleading guilty to dangerous driving.

Patrick Delsame was driving an unmarked police van in September 2011 when he hit a vehicle after weaving in and out of traffic on Highway 132 on Montreal's South Shore.

When one car did not change lanes to allow him to pass, Delsame drove up against its bumper.

Both vehicles stopped.

He then got out of the van, flashed his badge and punched the 17-year-old driver.

Delsame pleaded guilty to dangerous driving in 2013 and was fined $2,000.

In a July 27, 2016 ruling, Quebec's police ethics board — the Comité de déontologie policière — found Delsame's behaviour was unacceptable and violated the Sûreté du Québec's code of ethics.

The report states he did not challenge the decision to dismiss him.
