A man was arrested in connection with the crash on suspicion of arson, officials said. No injuries were reported.
A driver was arrested on Sunday for crashing a vehicle into a post office in San Jose, Calif., and setting the building ablaze, the authorities said.
Officials said the man, Richard Tillman, 44, is believed to be the youngest brother of Pat Tillman, the former professional football player turned Army Ranger who was killed in Afghanistan. Mr. Tillman was arrested on suspicion of arson, officials said. He was being held at the Santa Clara County jail.
Firefighters were called at about 3 a.m. Pacific time on Sunday to a post office in the Almaden Valley area of San Jose, where they found that a vehicle had plowed through the front of the building, the authorities said. It took them more than 90 minutes to extinguish the fire. No one was injured.
The crash is being investigated by the U.S. Postal Inspection Service and local law enforcement agencies. In a statement on Sunday, the Postal Inspection Service said that the crash was potentially intentional and that investigators were trying to determine a motive. The agency also said that Mr. Tillman was “reported to be the brother of” Pat Tillman, a star defensive back for the Arizona Cardinals who then enlisted in the U.S. Army after the Sept. 11, 2001, terrorist attacks.
It was not immediately clear whether Richard Tillman had legal representation. His family members declined to comment on Sunday.
“I’m grateful no one was seriously hurt by this senseless act of destruction,” Matt Mahan, the mayor of San Jose, said in a statement on Sunday. He also acknowledged that mental health issues could have been an underlying factor.
