At least two people were shot dead and seven others injured when gunmen opened fire in front of a Detroit barbershop at around 6.15 p.m. EST on Wednesday evening, police said.

According to a USA Today report, citing police officials, two cars followed each other exchanging gunshots when they reached the barbershop on the city’s east side.

"Somehow someone shot into the building, and that's when people rushed out of the building and were running into other area businesses for cover," police spokeswoman Kelly Miner said, Associated Press reported.

Police previously had said there were three deaths, but, later confirmed two fatalities. Both the dead men were found inside the barbershop.

Detroit Police Chief James Craig told reporters that more than one suspects and two cars could have been involved in the incident. Police are looking for a 2004 black Chevrolet Impala and a 2004 white Impala, which may have bullet marks on its back, USA Today reported.

Al's Barber Shop, where the shooting occurred, is known for illegal gambling activity, however, police said it is too early to confirm whether the shooting was related to gambling, AP reported.

"We're not sure if this was over a bad debt. We have no idea," Craig said. "We know it's a barbershop and gambling has occurred in this location."

Craig confirmed that all the victims were males but did not release the names or ages of the victims.
