TORONTO -- A motorcyclist has been seriously injured in a collision involving a truck in Scarborough Friday night.

Emergency crews were called to the intersection of Brimley and Mandarin Roads, north of St. Clair Avenue East, around 6 p.m.

Sgt. Zee Dhukai from Traffic Services told CP24 a motorcycle and a truck collided at the intersection.

Police initially said the motorcycle became involved in a second collision with another vehicle.

A man in his 30s was taken to a trauma centre in serious condition, paramedics said.

The driver of the truck remained at the scene, Dhukai said.
