Pennsylvania ? A man who had threatened a Christian radio station was shot and killed by police Friday after he fired at officers with a rifle and tried to run them over with his sport utility vehicle, authorities said.

WTLR station manager Mark VanOuse said the station received a tip around 10 a.m. that someone armed with a shotgun was asking people for the address of the radio station and for money. Police got the same tip and went to the station, Centre County District Attorney Michael Madeira said.

Officers intercepted the man as he arrived at the station, where he began shooting at police outside, ramming police cruisers and trying to run over officers on foot, witnesses said. After an exchange of gunfire, the suspect was shot dead in his white Ford Bronco, Madeira said. No one else was wounded.
