Two men travelling in a car together were injured by gunshots fired from a passing vehicle on Highway 403 over the weekend, police said.

The two men, aged 32 and 43, drove themselves to Etobicoke General Hospital after the shooting, arriving around 11 p.m. Sunday. A 19-year-old woman was also in the Chrysler 300 sedan, but she was not hurt.

Police could not comment on the exact nature of their injuries. The younger man was transferred to a trauma centre for treatment, while the elder man was treated at Etobicoke General. Both are in stable condition, police said.

The men were travelling on Highway 403 eastbound when those in a passing vehicle fired several shots at them near the exit ramp for eastbound Highway 401, according to police.

OPP officers attended the scene overnight, briefly closing the ramp to investigate. Peel police are now taking over the investigation.

No information about the suspect vehicle or its occupants were available as of early Monday morning.
