REDDING, Calif. -

A police car and an uninvolved vehicle collided during a late night pursuit on the streets of downtown Redding on Saturday night.

According to investigators, officers were chasing a 2000 Cadillac Escalde that had failed to stop for a mechanical violation.

The pursuit went through the areas of Wyndam Lane, the Parkview neighborhood, Park Marina Drive, and Continental Street.  The Cadillac continued west on Eureka Way and crossed Pine Street. 

According to the California Highway Patrol officer Aaron Hollemon, who was involved in the pursuit, entered the Eureka Way and Pine Street intersection with lights and sirens activated, and was struck by a vehicle not involved in the pursuit, which was traveling north on Pine Street. 

The crash, which is being investigated by the California Highway Patrol, was initially reported as non-injury, but the four occupants of the vehicle later requested to be transported to the hospital by ambulance due to complaints of pain, police said.

Officers continued pursuing the Cadillac which ultimately crashed in the area of Willis Street and Butte Street. The driver of the Escalade, described only as a black male adult, fled on foot and has not yet been located.

Anyone with information as to the identity of the driver of the Cadillac is asked to contact the Redding Police Department.
