The San Francisco Police Department is seeking an errant Razor Scooter rider for aggravated assault, after he rode into then beat up a man walking down the sidewalk.

It all went down at 2:25 Monday afternoon, police say, near the intersection of Van Ness Avenue and Hayes Street.

According to the SFPD, a man aged around 40-50 was Razoring down the sidewalk when he zoomed straight into a 54-year-old man.

Police say that the scooter-riding suspect then attacked the pedestrian, "striking him multiple times on his head and face."

The rough Razor rider then scooted off in an unknown direction, and hasn't been seen since. His victim was transported to an area hospital for treatment of his injuries, and as of Monday night remained in stable condition.
