WATCH: Video Shows Woman Brutally Attacked at Las Vegas Taco Shop

A woman says she was brutally attacked at a taco restaurant in Las Vegas by a man who had yelled a racial slur at her, KTNV-TV reports.

The assault was caught on the taco shop’s security cameras. You can see the video above.

Carmen Porter told the news station she stopped at the drive-thru of Roberto’s Taco Shop early Monday on her way home from work. Porter said she heard the attacker, who has not been identified, yell a racial slur at her as she drove away from the drive-thru.

“Part of me wanted to drive off and go home, but obviously a bigger part of me wanted to confront him,” Porter said. “I asked him, what did you just say to me, and (he) began shouting and saying ‘It is called freedom of speech. You heard me.'”

The video shows the attacker pick up a wet floor sign and hit Porter multiple times. The man then drops the sign and walks back into the restaurant. Porter said he went in to finish ordering food.

The assailant can be seen on video coming back out of the restaurant and picking up the sign to hit Porter again.

“I remember falling towards the rocks, and even when I was on my knees in the rocks he kept hitting me,” Porter said.

The man then was pulled away and left in a car. Police are investigating and trying to track down the attacker.

Las Vegas Police Lieutenant David Gordon told the Las Vegas Review-Journal that Porter is black and the attacker was white.

Gordon said it is not clear if the slur heard by Porter was directed at her. He told the newspaper the man left the scene in a light-colored sedan and was with two other men in their 20s, who did not take part in the assault.

Porter was taken to the hospital and said she received 15 stitches after the attack.
