OAKLAND -- Two teenagers were arrested, a third released and a fourth is still being sought after a police chase over a stolen car ended in a crash and the possible firing of a gun at officers Monday night, authorities said.

Officers attempting to pull over the newer model Acura around 8 p.m. Monday in East Oakland gave chase when the car sped up and eventually crashed into a home near the corner of 73rd Avenue and Orral Street, police said.

Arrested almost immediately were a 17-year-old boy believed to be the driver of a new model Acura police said was stolen in East Oakland after the owner left keys in its ignition, and another boy the same age who had fled on foot, police said.

The alleged driver was arrested on suspicion of auto theft, and both are also suspected of possessing stolen property. A 16-year-old boy riding in the car as a passenger was questioned and eventually released, police said.

Officers searching for a fourth suspect, believed to be 16 or 17 years old, reported hearing a gunshot as they searched, but it remained unclear this morning whether someone was shooting at them or a gun had been discharged accidentally.

Police sealed off the area and SWAT officers were called to the scene.

Investigators found a handgun in a yard behind the house where the crash happened, police said. It was not immediately clear whose gun it had been or who was holding it when it discharged.

The search for the fourth suspect was called off early this morning, police said.
