S.F. boy accused of robbing girl with cerebral palsy at gunpoint

A 14-year-old boy was arrested Monday for committing a series of robberies in San Francisco’s Western Addition neighborhood, with the latest crime involving a gun, police said.

The boy, whose name was not released because he is a minor, was booked into juvenile hall on suspicion of three robberies after police issued a bulletin with his picture — and a Northern station officer recognized him, authorities said.

The latest robbery targeted a 16-year-old girl with cerebral palsy, police said. The boy allegedly followed her off a bus as she was heading to school on June 9 and robbed her of her iPhone at gunpoint on the 1600 block of Turk Street.

Her iPhone and the gun have not been recovered.
