A Los Angeles Police Department sergeant was seriously injured in a motor vehicle crash Tuesday morning near the USC campus involving Inglewood Mayor James T. Butts Jr., law enforcement sources told the Los Angeles Times.

Butts was attempting to make a left turn onto the USC campus, possibly against a red light, when his vehicle was struck by another car, according to a law enforcement official who spoke on the condition of anonymity because the person was not authorized to discuss the case with the media.

Butts' vehicle then spun and collided with the sergeant, whose motorcycle was parked on the sidewalk. The force of the collision sent both the sergeant and his motorcycle into a nearby fountain, the law enforcement official said.

The crash is under investigation. No one has been cited in the incident at this time.

Sources said the sergeant suffered several broken bones after being struck by the SUV.
