At least three people were killed in a crash Friday that left cars mangled and debris scattered at an Upland intersection.

A Ford Mustang at the scene near 16th Street and Mountain Avenue had significant front-end damage. Another heavily damaged car ended up on a grassy embankment next to the road.

Details about the victims and what led to the crash were not immediately available. Authorities said the collision happened during a police pursuit.

The chase began at about 2 a.m. when a deputy in Rancho Cucamonga attempted a traffic stop. The driver failed to pull over, the sheriff’s department said. The chase entered Upland, where the driver collided with another car, according to the agency.
