Authorities are searching for the man who body slammed another man to ground, fracturing his skull, in a road rage fight that was caught on video.

The May 26 confrontation occurred on the side of the road near 4th Street and Ardmore Avenue in Koreatown. It was not immediately clear what led to the altercation, but police said it resulted from a "traffic dispute."

Both men can be seen squaring off in the middle of an intersection. Several punches and kicks were exchanged before the man sought in the attack picked up the victim and slammed him onto the sidewalk. The victim lost consciousness after his head struck the ground, police said.

"It's very difficult to watch. It shouldn't happen here in Los Angeles," said LAPD Officer Jack Richter. "Defending yourself is one thing."

The attacker continued to slam the victim's head onto the sidewalk before another individual broke up the fight, police said. The assailant then left in his vehicle, which was double-parked on 4th Street around the corner.

The victim suffered a fractured skull and internal bleeding, police said.

"He had a fractured skull, he was in in the hospital the whole time and remembers nothing of the incident," Richter said.

There were several witnesses to the fight and attack, but no one has been able to identify the attacker and no one got a license plate number before he fled, so police are asking for the public's help to find him.

"The issue needs to be solved," Richter said. "That person needs to answer for what happened."

Police described the attacker as Asian, in his mid to late 30s with black hair, approximately 5 feet, 8 inches tall and 180 pounds. He was wearing a white T-shirt, bluejeans, black shoes and a black baseball hat.

The man's car was described as an off-white, early model four-door sedan, possibly a Volvo, with a nonfunctioning left brake light.
