One person was shot and another was arrested in connection with the crime during a Friday night concert at a Cupertino bowling alley, according to the Santa Clara County Sheriff's Office.
The shooting occurred just after 10:30 p.m. at the X-Bar, which is inside the Homestead Bowl at 20990 Homestead Road, sheriff's deputies said.
A group of Bay Area rappers was performing when, witnesses say, some people entered the packed bar, began tossing chairs around and then opened fire.
One witness said he and his girlfriend ran to hide in a restroom as shots ricocheted throughout the space. After the gunshots quieted, the pair ran to the door and noticed a man with white shoes covered in blood, Faruk Farah said.
Sgt. Richard Glennon said at least two people began shooting at each other, striking an adult victim in the leg. The victim was treated at a local hospital for a non-life threatening injury.
During the investigation, deputies arrested one suspect and recovered two firearms, Glennon said.
Witnesses, neighbors and concert attendees with more information about the case are asked to contact the Santa Clara County Sheriff’s Office at 408-808-4500.
