Police are looking for a man who was seen on video punching another man at the Hollywood and Vine Metro Red Line station early Tuesday morning.

The incident happened at about 1 a.m. on the station platform. Bystander Lake Cunningham told KTLA that he saw an older black man and a younger white man get into a verbal argument and began recording them. The younger of the two men is seen removing a gray jacket and a white T-shirt before walking up to the older man and punching him in the head. The older man falls to the ground, not far from the tracks.

A portion of the video is obscured by a passerby in a gray coat walking through the frame, and Cunningham said his video does not depict the full attack. He claims that, after the punch, the younger man kicked the older man in the face.

“I followed [the victim] and he had no teeth in his mouth. He had his teeth knocked out and he was bleeding all over the place,” said Cunningham.

Cunningham called the police, but the victim, the alleged assailant, and the two men the attacker was with had all departed the station by the time authorities arrived, NBC Los Angeles reports. Cunningham did manage to get a photo of the younger man before he left.

Cunningham believes the victim was homeless, telling NBC, "You could tell he had some mental disabilities and he obviously wasn't a threat. There was no need for that kind of violence whatsoever."

Investigators are currently reviewing both Cunningham's recording as well as station surveillance at this time.

L.A. County Sheriff's Office Deputy Ramon Montenegro said via a statement, "You can see some verbal exchange, not sure if it was a verbal altercation. But whatever it was it didn’t warrant an assault because it didn’t appear the victim was a threat to the other gentleman.”

Anyone with information should contact the LASD at 888-950-7233.
