SAN DIEGO — Two people were detained Monday after a car chase left a California Highway Patrol officer injured in the Serra Mesa neighborhood, police said.

Shortly after midnight, CHP officers tried to pull over the driver of a red Acura MDX seen speeding and swerving on Interstate 805 near Murray Ridge Road, San Diego police said. The officers directed the driver to pull off onto Phyllis Street, and as officers started approaching the car, the driver made a U-turn and sped off, police said.

The officers learned the car, which had three people inside, had been stolen in a carjacking in Escondido and began chasing it, police said. After the driver turned onto Encino Avenue, a dead-end street, the officers got out of their vehicle.

When the driver made a U-turn and sped towards their patrol car, the officers fired their weapons, police said. The car hit a patrol car, pinning an officer between the two vehicles. The officers tried to follow the car but lost sight of it.

Officers found the car abandoned in the 2200 block of Royale Crescent Court. Officers detained a 21-year-old man suspected of driving the car and a 17-year-old girl found nearby. Police were still searching for a third person.

The CHP officer was taken to a hospital to be treated for minor injuries. He has since been released.
