The intersection of Brighton and Riverside streets in Portland is closed Saturday afternoon following a fatal car crash.

Portland police said a man died in the crash and they are looking to speak with anyone who helped the victim, according to News Center Maine (WCSH/WLBZ). The crash happened shortly after 1:30 p.m. when a car hit two other cars that were stopped at a traffic light on Brighton Avenue.

Lt. Robert Martin told News Center that a person driving one of the cars got out of his car, stumbled to the middle of the intersection and collapsed. He was found dead by first responders. Martin did not know which car the victim had been in.

Police have not released any other details about the person who was killed.

Two people in one of the other cars involved in the crash were taken to the hospital with injuries, police said.

“We believe there are at least two more witnesses who could provide us with crucial information to determine what happened,” Martin told News Center.

The body of the victim will be taken to the state Medical Examiner’s Office for an autopsy Sunday that is expected to determine the cause of death, police said.

Police advised drivers to avoid the area until further notice while they investigate.

No other details were immediately available.
