A man described as a "one-man crime wave" by police was arrested this week after he apparently told inmates too much while being held in the Alexandria jail.

Andrew Timothy Russell, 24, of Landover was charged with helping to commit three armed bank robberies, an armed robbery against a citizen and two abductions within a span ov seven weeks last summer, Fairfax County police spokeswoman Carolyn Burns said yesterday.

According to a District of Columbia robbery investigator, an informant told police that Russell was being held in the Alexandria jail on a grand larceny charge under the false name of "Foster" and had told inmates about the bank holdups.

Fairfax investigators then used a photograph of the suspect and descriptions supplied by the victims to identify the suspect at the jail, spokesmen said.

Russell, an unemployed resident of Capital View Drive, now is being held at the Fairfax jail in lieu of $300,000 bond. Fairfax police said two other individuals also are being sought in connection with the crimes in an investigation that includes the FBI and Prince George's County police.

Each of the incidents, which occurred between June 6 and July 28, involved two men who frequently were dressed in gray sweat suits, police said. All occurred within minutes of the Capital Beltway, a quick escape route, and transpired in the early afternoon hours, Burns said.

On June 6, two men robbed the Washington and Lee Savings and Loan on Bland Street in Springfield of an undisclosed amount of cash, escaping in a van after abducting and tying up the vehicle's owner, Burns said. Two men fitting the same description robbed the bank again at 4 p.m. on July 25.

On June 23, the two suspects allegedly abducted a man near the Yorktown Shopping Center on Gallows Road, forced him into his car at gunpoint, and then drove the 33-year-old victim to a spot behind Luther Jackson Intermediate School. Then, Burns said, one of the suspects drove back to the shopping center to buy rope and left the victim tied to a tree.

On July 28, two men fitting the same description robbed the Virginia National Bank at the Yorktown Shopping Center, escaping with an undisclosed amount of money, Burns said.

In each of the bank robberies, Burns said, one of the suspects was armed and announced a holdup, while the second man leaped across the bank counter to steal the cash.

Police said Russell also is under investigation in connection with two armed robberies committed in Prince George's County.
