The assault occurred in the 6900 block of Noritsu Avenue around 8:19 a.m.
According to authorities, the incident began when the officer spotted the driver in a stolen dark colored GMC Acadia near Magnolia Avenue and the 91 Freeway.
The driver, later identified as Andrew Christian Stewart, attempted to flee but shortly exited the freeway at Knott Avenue and the 91 Freeway.
The pursuit then surfaced on the streets as Stewart proceeded westbound before approaching Noritsu Avenue which is a dead-end street.
As the officer exited his vehicle to approach the suspect and a second female passenger, Stewart accelerated, striking the officer and momentarily pinning him to his patrol car.
Stewart fled the scene during the ordeal. The injured officer got back in his patrol car to chase the suspect but soon lost sight of him.
An extensive search of the area and surrounding neighborhoods was also conducted to no avail. The stolen vehicle was found abandoned on the 7000 block of Valley View Street shortly after the pursuit.
Stewart is considered armed and dangerous. According to police, the suspect is a known narcotics user and was recently arrested for possession of a loaded firearm.
Anyone with information on Stewart's whereabouts or his female accomplice was urged to contact Detective Burciaga at (855) TIP-OCCS.
