We have new information on a disturbing armed robbery.

The FBI told us tonight that a bank robber in Northern Idaho is known as the AK-47 Bandit and has pulled off bank heists in other states.  

Police in Rexburg say the robber threatened employees and customers at a credit union with what looked like an assault rifle and locked them in a safe yesterday.  

Rexburg is in the northeast corner of Idaho.

Witnesses described the suspect as 5'10", 225 pounds.  He was wearing a mask, black gloves, a black coat with a hood and baggy levi jeans.

Witnesses say he drove off in a dark blue sedan with tinted windows and a red and blue license plate.

The FBI says rewards are being offered in this investigation.  

If you have any information, you're urged to call your local law enforcement.
