It was unclear what prompted police to open fire, or if the suspect was struck. No officers were injured, according to a spokesperson for the city of San Gabriel.
Authorities confirmed the chase began at 4:06 a.m. and ended four minutes later, when the suspect exited a vehicle and fled on foot.
Investigators searched for the suspect for hours in the area of Del Mar Avenue and the 10 Freeway, which was partially closed at the scene.

A San Gabriel Police Department spokesperson said the man was initially wanted for a possible vehicle code violation.
Los Angeles County Sheriff's Department deputies assisted in the search, and K-9 units were requested. Residents were advised to remain in their homes or avoid the area.
The suspect was described as a Hispanic man in his mid 20s, 5 feet 8 inches tall, 175 pounds, with black hair and brown eyes. He was taken into custody around 9:30 a.m., though his identity was not immediately released.
