A car caught fire in Richland around midnight Monday after a homemade bomb went off inside it, police say.
Richland police responded to the 100 block of Riverwood Street where they found two homemade bombs in two separate vehicles, one of which did not go off.
Richland firefighters found a tennis ball on the driver's seat of the car that caught fire. The ball appeared to be filled with a substance that caused the explosion.
Police searched the neighborhood and found a pick-up truck that had its windows broken out. Police say they found a device the size of a ping-pong ball inside the truck. The device was filled with BB's and had nails on the outside of it, as well as a partially burned fuse.
The Richland Police Bomb Squad and an arson investigator were called to the scene. Bomb technicians checked the two devices, and rendered them safe.
Police say twelve other cars on the street were also damaged by the explosion.
