An angry motorcyclist remains at large today, after police say he used his helmet to assault a man during a Sunset District dispute.

Police say that the incident went down on the 700 block of Irving Street, which is between Eighth and Ninth Avenues, at 4:57 p.m. Wednesday.

According to the San Francisco Police Department, two men in their late 30s were arguing with the 40-year-old male victim. As the argument escalated, police say that one of the pair of men hit the victim with a motorcycle helmet, then stole the injured man's phone.

Police say that the suspects then fled by motorcycle from the scene.

The victim was transported to San Francisco General Hospital for injuries police say are not life threatening. The suspects remain at large, and police confirm that as of Thursday morning, no arrests have been made in the case.
