Updated, 4:15 p.m. Thursday:
Michael W. Moore Jr. has been arrested and charged in Tuesday's credit union robbery, according to documents filed in federal court for the District of Alaska.
Moore was allegedly the driver of the vehicle used in the robbery, federal prosecutors say.
The Anchorage Police Department used video surveillance to track down the vehicle — a red 1998 Chevrolet Lumina — in the robbery. Police found the car as it was backing out of a driveway, with Moore inside.
Moore told police that he had driven his girlfriend's car to Wasilla "to purchase illegal narcotics" and said he didn't know anything about the robbery.
Investigators found $1,000 in $100 bills that "appeared new" in Moore's wallet. In he car, police found an "improvised mask" made from a sleeve of a shirt that was inside a plastic grocery bag along with black sweatpants and a black jacket. They also found a patterned camouflage hooded sweatshirt and two cellphones.
Police also found $480 in cash inside a black purse. In the room Moore shared with his girlfriend, police found $3,150.
Moore has been convicted of bank robbery three times previously, court documents say.
A credit union in Midtown Anchorage was robbed Tuesday afternoon and the FBI is asking for the public's help in finding the suspect.
Just after 1 p.m., a man entered the Credit Union 1 at 3525 Eureka Street with a gun and demanded money, FBI spokeswoman Staci Feger-Pellessier said in a written statement.
The suspect was described roughly 6 feet tall, wearing a green mask, a camouflage print jacket, blue jeans, and red shoes. He was carrying a black Nike bag.
The man left the scene in a blue car, heading west "with an undisclosed amount of money," Feger-Pellessier said.
The same credit union was robbed on Feb. 10, according to the FBI.
Anyone with information about Tuesday's robbery was asked to call the FBI at 907-276-4441.
Correction: An earlier version of this story incorrectly reported that Moore was suspected of entering the credit union with a gun. He is accused of being the driver of the vehicle used in the robbery.
