Officers were dispatched to a shooting in the 1700 block of Telegraph Avenue at 4:10 p.m. Saturday, Oakland police Officer Johnna Watson said.
Prior to the shooting, the suspect allegedly broke into a car, stole items and fled, Watson said.
Police said witnesses chased down the suspect and recovered the property. The suspect then returned to the scene on a bicycle with a firearm.
He allegedly shot two women and two men then fled the scene, Watson said.
All four victims suffered gunshot wounds that are not considered life-threatening, according to police.
Police eventually arrested the suspect but have not released his identity pending review of the case by the Alameda County District Attorney's Office.
