One person has been shot and three others injured following a fight outside a Sacramento nightclub.

Police say a security guard shot a passenger in an SUV that hit two people as it sped away early Saturday from the Costa Azul nightclub.

The SUV driver flagged down a Sacramento Fire Department ambulance several blocks from the nightclub to get aid for the passenger, who was hit in the wrist. Ambulance personnel called police, who arrested the driver on suspicion of hit and run and drunken driving.

The two people hit by the SUV were hospitalized with moderate injuries. A security guard who was also struck by the vehicle had minor injuries.
