A 60-year-old man was critically injured when he hit his head on the sidewalk after being punched in San Francisco’s Tenderloin neighborhood on Monday night, police said.
The attack, which police said appears to have been unprovoked, was reported at 9:51 p.m. in the first block of Turk Street, which is near Market Street.
The victim was standing in that block when the suspect rode up to him on a beach cruiser bike, according to police.
The suspect “struck him one time in the chest area with his fist, and it caused the victim to fall backwards and strike his head on the sidewalk,” police Sgt. Danielle Newman said.
Officers arrived to find the victim bleeding from life-threatening head wounds, police said. He was taken to San Francisco General Hospital, where he remained in critical condition this morning.
The suspect, described as a man in his mid- to late 20s, remains at large, Newman said.
Investigators are canvassing the neighborhood looking for potential witnesses and any surveillance video footage of the assault, police said.
Anyone with information on the case is asked to call the Police Department’s anonymous tip line at (415) 575-4444 or text a tip to TIP411, with “SFPD” in the message.
