Authorities say a suspect was arrested after a car crashed into a post office in San Jose, California, causing the building to go up in flames.

A man was arrested in connection with the crash on suspicion of arson, officials said. No injuries were reported.

Fire crews responded to a fire at a South San Jose post office early Sunday morning, the San Jose Fire Department said. The fire happened just before 3 a.m. on the 6500 block of Crown Boulevard. A photo shared by the Fire Department shows what appears to be a vehicle inside the building. But the agency has not yet said what started the fire.
