San Jose man convicted of transporting AK-47 was arrested for trying to trigger dummy explosives in Oakland, FBI says.

The FBI arrested a California ex-convict early Friday as he allegedly tried to blow up a Bank of America branch in Oakland, hoping to start a civil war.

Matthew Aaron Llaneza, 28, of San Jose, was detained after he tried using a cellphone to detonate an explosives-packed SUV at a BofA branch near the Oakland Airport, the FBI said. Agents had created a dummy bomb, however.
