Oakland police were investigating a shooting at Highland Hospital on Monday night, authorities said.

No one was hurt and no one was arrested in the incident that took place about 8 p.m. near the hospital’s ambulance bay at 1411 E. 31st St., police said.

ShotSpotter, the city’s gunfire-detection system, recorded 25 to 30 shots. A sergeant reported the gunfire, saying, “Code 33 at Highland, shots fired,” using police code for emergency.

The sergeant reported seeing a gold Dodge Stratus leaving the hospital after the shooting and heading toward 14th Avenue.

“There’s a bunch of shots fired. Get as many units as (you) can,” the sergeant instructed dispatchers.

Alameda County sheriff’s deputies stopped the vehicle at 14th Avenue and East 17th Street and determined that the occupants weren’t suspects but were either trying to get away from the gunfire or were the intended victims, police said.

Police were already at the hospital on an unrelated matter involving the medical clearance of a suspect, said Oakland police Capt. Ersie Joyner.

The hospital, which is south of Interstate 580, treats most of the city’s gunshot victims.
