Authorities are looking for more information Friday after video surfaced of a woman beating a man on the Metro Blue Line in Long Beach after he allegedly yelled racial epithets at her.

The one-and-a-half-minute video, posted around 7:30 p.m. Monday, shows a woman punching an allegedly drunk man, before climbing on her seat and stomping him repeatedly. The woman then stands on top of the man, kicks him and jumps up and down on his back and head.

A passenger can be heard yelling "don't kill him now," as the woman, dressed in black legging with marijuana leaf designs, kicks the man.

The woman exited the train at the fifth street station in Long Beach.

Witness Keith Rachel told KTLA the incident began at the Willowbrook station when the two got into an argument over a seat. The altercation turned physical after they got on the bus, according to Rachel.

The Los Angeles Sheriff's Department has identified the man who recorded the video and hope that he may have more information on the incident.

Authorities were not aware of the assault until the video was posted on Facebook and it was never reported to police, according to the Los Angeles Times.

"Her reaction was valid, however, killing the man almost, I don''t think that was right," said security guard Gordon Flowers.

LASD spokesperson Ramon Montenegro told the Times that the attack was “excessive” and deputies could have intervened and cited the man if the woman had reported the alleged behavior to police.

The investigation is ongoing.
