A 54-year-old man has been arrested on suspicion of throwing Molotov cocktails at the Los Angeles Federal Building, authorities said Tuesday. Nobody was hurt.

Security guards heard a man yelling derogatory comments about U.S. Immigration and Customs Enforcement outside the downtown building on Monday, according to a statement by the U.S. Department of Homeland Security.

He then hurled two incendiary devices at the guards, the department said.

�Fortunately, the bottles were not lit and did not catch fire and there were no injuries or damage to federal property,� the DHS statement said.

FBI agents arrested Jose F. Jovel, of Los Angeles, said bureau spokesperson Laura Eimiller. She said federal prosecutors were expected to file a criminal complaint on Tuesday.

It wasn’t known Tuesday if Jovel has an attorney. The Federal Public Defender’s Office didn’t immediately respond to a phone call asking if one of its attorneys is representing him.

Jovel, who had four knives on him when he was arrested, has an �extensive criminal history,� including an attempted murder charge in 1987, the DHS statement said.

Messages were sent to the U.S. Attorney’s Office seeking additional details.
