Surveillance cameras captured this image of the so-called "AK-47 Bandit" as he exited a Chino bank in February 2012.
Tips leading to the arrest of the so-called "AK-47 Bandit," wanted in a slew of bank heists across the western United States, could result in a $100,000 reward, the FBI announced Wednesday.
"This guy, he’s a time bomb about to go off again," Bill Lewis, head of the FBI office in Los Angeles, said in a news conference.
Prior to Wednesday, a $50,000 reward had been posted for the arrest of the prolific bank robber suspected of shooting a Chino police officer during a heist in February 2012, before hitting up banks in Northern California, Idaho and Washington. He was dubbed the "AK-47 Bandit" because of his penchant to carry the assault rifle into his targeted banks.

Investigators said he has told victims that he used to be an officer, and surveillance video shows him usually wearing tactical gear, a full-face ski mask and blue ballistic vest or green mesh vest marked "Sheriff."
After robbing the California Bank & Trust in Chino early last year, the man is believed to have robbed a Vacaville Bank of the West on March 12, 2012. He may have also tried to rob a bank in Sacramento a few days earlier.
Similar robberies were carried out in Washington on July 6, 2012, and Idaho on Nov. 7, 2012.
The “AK-47 Bandit” is described as a white male, 25 to 40 years old, about 5 feet 10 inches tall and weighing between 180 and 200 pounds.
