Waukesha, Wisconsin - Bank robber needed the money to buy a watch. It would seem he needed one after arriving six minutes after the Guardian Credit Union in Waukesha closed.

Police said a man wearing a ski mask entered the first set of doors at 5:36 p.m. Wednesday with a gun, apparently not realizing the bank was closed.

The second set of doors was locked and police were called but the man left before they arrived. Waukesha Police Sgt. Jerry Habanek told The Freeman in Waukesha that police are reviewing security tapes and investigating.

He said the robber could have planned poorly or possibly had another reason, like getting tied up in traffic.
