The FBI is searching for two men suspected of robbing at least three Denver-area banks during the last two months.
At least one of the suspects is known to be armed.
FBI agents have released security photos to the public, hoping that someone will recognize the suspects.
At an October robbery of a TCF Bank in Arvada, cameras captured an image of one of the suspects leaping over a teller counter. He wore a black wig, blue jeans, a green hooded camo jacket, and gloves.
The FBI believes that just 15 minutes earlier, the same suspect attempted to rob a Wachovia in Wheat Ridge.
On Nov. 28, two suspects robbed a TCF Bank in Westminster. They wore hooded sweatshirts during the robbery.
Investigators also believe that earlier this week the same suspects robbed a TCF Bank in Westminster.
