A man -- possibly armed -- barricaded himself inside a Baltimore-area TV station Tuesday after chanting "I am God" and then repeatedly ramming a dump truck into the building.
WMAR-TV meteorologist Mike Masco tweets that the staff had been evacuated and that everyone at the station appeared to be safe.
"Guy kept chanting I am God when he first walked up to the door of the building. went back for his industrial sized truck and rammed building," Masco tweets.
WMAR quotes police as saying the man was seen wearing a backpack, raising the fears that he may be armed.
Masco also reported that police found weapons in his vehicle.
Brian Kuebler, of ABC2, is also tweeting from the scene, saying the suspect got into a landscaping truck and rammed the building three times before breaking into the lobby. He says the company reports that the truck was stolen.
