Authorities continue to search for a man who held up a credit union inside a Cheyenne Safeway store last Monday.

Laramie County Sheriff's Department Captain Linda Gesell says the man was a transient who may have gotten away in a teal and white 1970s model Volkswagen camper bus with Colorado plates.

Gesell says they are working with the Federal Bureau of Investigation to try and determine who the van is registered to.

Anyone with information is asked to contact the Cheyenne F.B.I. Office at (307) 632-6224 or the Laramie County Sheriff's Department at (307) 637-6524.
