FBI: 2 brothers suspected in 4 bank robberies - Vyacheslav Volkov and Denis Volkov

DENVER - The FBI is asking for the public's help to find two brothers accused of robbing four metro area banks in 10 days.

Investigators say the "Brothers Bandits" walk into a bank, use a weapon to demand money and flee.

The FBI has identified the suspects as Vyacheslav and Denis Volkov.

Vyacheslav is 31. He is a white man, 6'1", 200 pounds and speaks with a heavy accent.

His brother Denis is 19. He is a white man, 5'8", 160 pounds with no noticeable accent, according to the FBI.

Both are charged with armed bank robbery and aiding and abetting, according to federal records.

"We don't know if there is some encouraging going on, but they are definitely a duo to be dealt with," said FBI spokesman Dave Joly.

Joly said the brothers are considered armed and dangerous.

"Bank robbers often will continue to commit bank robberies until they're caught," he said. "And a lot of times they get more brazen along the way."

The "Brothers Bandits" are suspected of robbing the U.S. Bank on Quebec in Denver on August 3, the U.S. Bank on 88th in Westminster in August 5, the U.S. Bank on 120th in Thornton Monday and the TCF Bank on Broadway in Denver Tuesday night.
