An arrest has been made after authorities say a driver intentionally rammed another car in Southern California, killing three teenage boys and injuring three others.

The California Highway Patrol says the Toyota Prius was hit Sunday night in Temescal Valley, went off the road and slammed into a tree. Three boys died and three had moderate injuries.

A witness followed the other car and CHP officers arrested 42-year-old Anurag Chandra of Corona in a neighborhood near the accident scene. He was booked on suspicion of murder with malice.

It's unclear whether he has an attorney.
