A motorcyclist is in hospital with serious head injuries after he crashed on the Alexandra Bridge while trying to avoid Gatineau police.

A Gatineau police spokesman said police began a pursuit of the rider of the motorcycle after a traffic infraction at Sacre-Coeur Boulevard and Laval Street in the Hull sector of Gatineau.

During the pursuit, police said the motorcyclist committed a number of other traffic offences.

Police broke off pursuit before the motorcycle reached the bridge, according to the police spokesman.

The motorcycle then collided with a van on the bridge leading into Ottawa around 2:40 p.m.

Ottawa paramedics said the 26-year-old motorcyclist was unconscious but regained consciousness by the time they arrived. He was also treated for abrasions to his upper body and legs.

The driver of the van was not injured.

At least one witness told Ottawa police the motorcycle was fleeing Gatineau police.

Ottawa police are now investigating the incident.
