An Illinois man accused of robbing a Bettendorf credit union last month has been indicted in federal court.

A federal grand jury on Tuesday returned a one-count indictment against Anthony Javon Brown, 32, of Bloomington, Illinois, in U.S. District Court, Davenport. 

He is charged with bank robbery, punishable by up to 20 years in prison. As of Thursday, Brown has not yet appeared on the charge.

Bettendorf police were called about 11 a.m. Aug. 18 to Ascentra Credit Union, 1710 Grant St., for a report of a robbery.

According to federal court documents:

A man, later identified as Brown, walked into the credit union wearing a black floppy hat, black sweatshirt, blue jeans and black Nike shoes with a white "swoosh."

Brown waited in the lobby until other customers conducting business left. While waiting, he retrieved a credit union form that is used for deposits, withdrawals and fund transfers.

He held onto the form in his bare hands while waiting in line. He then approached the counter and made a verbal demand for money from the teller.

He produced a paper bag, which the teller filled with $4,646. He retrieved the bag but left the form at the teller's window. He left in a gold/brown Chevrolet Impala that was parked in an adjacent lot.

Officers determined that fingerprints found on the transaction form belonged to Brown.

They also compared Brown's driver's license photo to still images taken from surveillance footage at the time of the robbery.

On Aug. 23, police arrested Brown at his relative's home in Bloomington. Officers found clothing that appeared to be similar to those worn by the credit union robber.

They also found $3,031 in the pocket of a black sweatshirt that was recovered. Part of the money was in a plastic bag, while some was in a cup inside another bag.

Officers also located a 2003 Chevrolet Impala, registered to Brown, in the driveway. Inside, they found a hat similar to the one worn during the credit union robbery.

The next day, Brown was interviewed by Bettendorf police and the FBI at the McLean County Jail. Brown said during the interview that he robbed the credit union and that he used some of the money on food, gas, marijuana and a trip to St. Louis, according to court documents.

Brown initially faced charges of first-degree theft and third-degree robbery in Scott County District Court. Prosecutors filed a motion to dismiss the charges Aug. 31 when Brown was first charged by criminal complaint in federal court.
