A gunshot rang out during an argument in a Brantford parking lot, police say.

Police officers were called to the lot, outside a townhouse complex on Darling Street, around 5 p.m. Monday.

It is believed that three men were in an argument in the parking lot, during which one of the men pulled out a gun and fired it.

Police were unable to find any evidence that the shot had hit any person or damaged any object.

Investigators are looking to talk to three people, all of whom they believe knew each other prior to Monday, about the incident.

One of the men is described as being slim, white and in his 20s. He was seen wearing a blue hoodie, brown pants, black shoes and a baseball cap, and was last seen heading toward Darling Street.

A second man is said to be black and in his 20s, with medium-length black hair. Police say he was wearing a black T-shirt, dark jeans and light-coloured shoes, and was last seen riding a mountain bike toward Darling Street.

Police describe the third man as having a tan complexion and slim build, as well as short, dark hair, a goatee and a thin beard. They say he is likely in his 20s, was seen wearing a black T-shirt, dark jeans and white shoes, and was last seen headed westbound on Stanley Street on foot.
