About 700 people were attending a funeral inside the Islamic Center of America in Dearborn, the largest mosque in metro Detroit, when Dearborn police arrived to arrest a man in a car in the parking lot.

He had driven to Michigan from California and reportedly was overheard in a bar making threatening comments about Muslims or Arabs. His car was loaded with large, illegal fireworks, police said. Now, Roger Stockham, 63, is jailed on charges that include making a false report or threat of terrorism.

"He's very dangerous," said Dearborn Police Chief Ron Haddad.

A decorated Army veteran accused of plotting to blow up a Metro Detroit mosque served time in federal prison for threatening to kill President George W. Bush and bomb a Vermont veterans' clinic in 2002.

In the Vermont incident, he told authorities at the time of his arrest at a Veterans Affairs Department complex in Colchester that his minivan was full of explosives. A search found no explosives.

Before the arrest, Stockham called a local paper twice to say he was going to explode bombs in the neighborhood. In one call, he identified himself as "Hem Ahadin," saying he was "a local Muslim terrorist on a roll."

He ranted against the VA, the FBI and Bush, largely because of the things the president had said about Iraq in a speech earlier in the week.

According to affidavit filed in U.S. District Court, Stockham threatened to carry out "jihad," or holy war, against the VA office in White River, Vt.
