Peel police on Sunday released images of a man they say purposefully drove into a group of people during a brawl that began in a Mississauga bar and spilled out onto the street.

Five people were injured by the driver, including a 23-year-old woman who was taken to a trauma centre with serious, but non-life-threatening, injuries.

The other victims were two women and two men, all in their 20s. All were treated for minor injuries, Peel Regional Police said.

Officers were initially called to &Company Resto Bar, near Burnhamthorpe Road W. and Hurontario Street, shortly before 3 a.m. for reports of a fight.

The incident started as an altercation between two groups inside the establishment, Const. Sarah Patten said.

Security staff escorted the patrons outside and the fight continued on the street and sidewalk. Police have not determined what the fight was about.

A man involved in the fight then got into his vehicle, parked the vehicle beside the bar, got out and fought some more.

"Then shortly after, he got back into his vehicle and drove directly at the people still involved in the fight," Patten told CBC Toronto.

The driver drove the vehicle onto the sidewalk, striking a crowd of people, she added. Some of the people he struck may have been bystanders. He then fled the area.

Vehicle described as dark-coloured Acura, no front plate

Patten said the suspect and vehicle are still outstanding.

He is described as about five-feet, six-inches tall and between 35 and 40 years old.

On Sunday evening, Peel police released several images of the suspect taken from security camera video.

His vehicle is believed to be a dark-coloured Acura, but she did not release a licence plate number. Police are not sure if the vehicle suffered damage to its front end from the collision.

"I've been told that it does not have a front plate," Patten said.

Officers have interviewed several witnesses and are reviewing surveillance video from the bar. Officers were canvassing the area for evidence.

People involved in the fight are co-operating with police, she added.

If the driver is found, he could be charged with assault with a weapon and failure to remain, Patten said.

Anyone who has information or witnessed the fight and ensuing collision is urged to call Peel police's criminal investigation bureau.
