MONTREAL -- A minivan hit a garbage truck, injuring a garbage collector, in Pointe-St-Charles on Tuesday, police said.

Around 3:30 p.m., the driver of the minivan, a 69-year-old man, lost control of his vehicle and hit the garbage truck from behind, temporarily pinning a 22-year-old garbage collector, a Montreal police spokesperson said.

Emergency vehicles rushed to the scene, near the corner of Charon and le Ber streets, after a witness called 911.
