PALO ALTO, Calif. (KRON) — A gunman fired bullets into an upscale restaurant at Stanford Shopping Center around 5 p.m. Monday, Palo Alto police said. Police are investigating the incident, which has been characterized as a drive-by shooting.

No one was injured inside Fleming’s Prime Steakhouse.

“The scene is secure. Initial info indicates the suspect fired a handgun from a moving vehicle. Unknown motive or target at this point,” the Palo Alto Police Department wrote.

Officers responded to a call from an employee of the steakhouse at around 4:25 p.m. on Monday. Officers responded immediately and confirmed that a large plate glass window near the front door had been struck by gunfire, police said in a press release.

The restaurant was open for business at the time and customers were inside. Bullet casings from a handgun were found in the ensuing investigation. Police also say they located a witness who reported seeing the suspect sticking a handgun out the driver’s window of a vehicle.

The suspect’s vehicle was a black Chevrolet Camaro that sped away northbound on El Camino Real, according to police. The witness was unable to describe the suspect. Another unoccupied vehicle that was struck by gunfire was later located parked near the restaurant.
