A man who was seen on surveillance video attacking a woman for no apparent reason at a Gardena gas station, inflicting facial and head injuries, was in custody this morning.

The suspect was turned in by a concerned family member and arrested Friday in Long Beach, according to ABC7.

The attack occurred at a Sinclair station in the 500 block of Rosecrans Avenue, near Figueroa Street, about 7:10 p.m. last Saturday, according to the Los Angeles County Sheriff’s Department, which confirmed the man was in custody.

The victim was pumping gas into her Honda Civic when the unidentified man parked directly in front of her, got out of his SUV, silently approached and punched her, knocking her to the ground, said Deputy Grace Medrano.

While she was on the ground, he repeatedly punched her in the face, grabbed her hair and slammed her head against her vehicle and the ground multiple times.

Video footage shows several men approach the suspect while the woman was still on the ground, and one touches the assailant’s arm, before he walks calmly back to his vehicle and drives away.

The woman, whose name was not released, told deputies she did not recognize the shirtless, 300-plus pound man and that he didn’t take any personal property from her, sheriff’s officials said.

She was taken to a hospital for treatment of serious injuries to her face and head, but has since been released and is recuperating at home, Medrano said.

After the release of the video of the Gardena beating, a second woman came forward to say she was also attacked by the suspect the same day, according to the sheriff’s department.

The 63-year-old woman told deputies she sustained minor injuries when she was attacked in Willowbrook, near the intersection of Rosecrans Avenue and Avalon Boulevard, on Saturday May 29.
