Police say the person who robbed a west side bank Monday was so heavily disguised that they aren't even sure if it was a man or a woman.

The crime happened at the Wells Fargo Bank in the 500 block of W. Garden of the Gods Road at 9:56 a.m. on June 16, 2014.

Police say the robber threatened a teller but no weapon was displayed.

The robber was about 6-feet tall with a medium to heavy build and was wearing blue clothes and possibly a wig.

Police say the robber got away on a bicycle and was last seen riding northbound on Chestnut Street.
