The FBI is asking for the public’s help to find a man who robbed a bank in Wyoming and who might be connected to a 1970s Volkswagen micro bus with Colorado license plates.

The armed robber, wearing a light blue surgical mask and a knit cap, held up the Warren Federal Credit Union in Cheyenne about 11 a.m. Feb. 29. The credit union is inside a Safeway at 700 S. Greeley Highway.

The robber made off with an undetermined amount of cash, according to an FBI media release.

The robber is described by the FBI as a white man, about 6 feet tall and 185 pounds. He fled the scene in a red, early 1990s Ford Taurus driven by light-skinned black man. There was another passenger in the vehicle who was not described.

The bank robber might be connected to a light blue/teal and white 1970’s Volkswagen micro bus with a Colorado license plate, the FBI said. The bus had a spare tire mounted to the front end and featured a flower or pattern design.

Anyone with information on the robbery, the suspects, or a suspect vehicle, is asked to call the Cheyenne FBI Office at 307-632-6224 or the Laramie County Sheriff’s Office at 307-637-6524.
