A vicious attack by four suspects at a 7-11 convenience store in Fremont, WA, has left the clerk and a customer hospitalized.

Surveillance video shows the suspects attacking the store clerk in Seattle’s Fremont neighborhood and an Indian American customer, Baljinder Kaur, 55, jumping in to try and help.

The clerk suffered a cut to the head. Kaur also suffered injuries to her face. Two days after leaving the hospital, she was still in great pain, according to her son Deep Singh, who told KIRO 7 he planned to take his mother back to the hospital.

Singh told the news station it was unlike his mother to step into the midst of a battle.

“She saw the two people hitting one person. They were hitting him on the head and he trying to close the door,” he said.

"And they start punching her on the face and everything," he said. "Yeah, and my mother and the clerk. She was brave. Like she's trying to stop them, with the four people."

He says his 55-year-old mother continued to fight even after the clerk was knocked unconscious.

Investigators are still trying to track down the suspects.
