The FBI is asking the public for help identifying the "Glamour Shot Bandit" -- a robber wanted for targeting six Denver banks in the last three weeks.
Investigators said the woman, believed to be in her 20s, earned the moniker because she wore heavy makeup, large hats, big sunglasses and gloves during the robberies.
The FBI warns that her "level of violence is intensifying" because she showed a handgun in one robbery and targeted multiple banks in one day.
The six robberies or attempted robberies at Denver banks span from March 22 through April 9, the FBI said. The most recent three crimes all occurred within two hours on April 9.
Anyone with information is urged to call the FBI or CRIMESTOPPERS at 720-913-STOP (7867).
A $2,000 reward has been offered.
