Police are on the lookout for three people who beat up a cab driver on Tuesday night.

Around 11:30 p.m., a taxi driver picked up two men and a woman at a grocery store on the corner of Upper Paradise and Mohawk Road West. They asked to be driven to a townhouse on Limeridge Road West, police say.

Once there, each person said they didn't have any cash, and asked the driver to come to one of the units to be paid. He agreed, but once they were in front of the unit the three people threw the driver to the ground and started punching him, police say.

After the assault, the three people ran off, police say.

Const. Debbie McGreal-Dinning told CBC Hamilton that there is no indication that they stole anything from the driver. "But they definitely did not pay their fare," she said. There's no indication they lived at this address, she added.

The victim slumped on the ground until an area resident noticed the cab out front, and called 911 when he saw the driver on the ground.

The 55-year-old male victim was taken to hospital with serious but non-life threatening injuries.

Police are asking anyone with information to call police at 905-546-3873 or Crime Stoppers at 1-800-222-8477.
