The Sureté du Quebec has fired an officer, a year and a half after the Public Security Minister said he should lose his job.

The firing stems from a 2011 incident where Patrick Delsame ran a 17-year-old driver off the road.

While driving a police van on Highway 132 in Saint Lambert, Delsame tailgated another car at high speed and then smashed that car into a concrete wall.

Witnesses said Delsame then struck the injured teenager as he staggered out of the wreckage of his car.

Delsame, who worked in the special investigation section of the SQ, was on his way to a training seminar.

In 2013 Delsame was found guilty of reckless driving and multiple breaches of the police code of ethics.

In December 2014, a Sureté du Quebec ethics committee recommended Delsame be fired, while taking note that Delsame has Attention Deficit Disorder and had stopped taking medication to control the condition.

The following month SQ director Martin Prud'homme asked Public Security Minister Lise Theriault to approve the decision.

She did so, but for unknown reasons it took another 18 months for the SQ to actually dismiss Delsame.
