UPDATE: Cross-Dressing Suspect Robs Monrovia Bank, Threatens Tellers with Anthrax

A cross-dressing man robbed the Chase Bank on Huntington Drive Wednesday and allegedly threatened bank tellers with anthrax, police said.

A male suspect "dressed as a woman" walked into the bank branch after 10 a.m. Wednesday, demanded money and said he had a briefcase full of anthrax, Monrovia Police Lt. Michael Lee said.

"He said there was anthrax in the briefcase, please give me the money," Lee said. "He took the briefcase and fled."

The suspect was wearing a woman's running suit and Ugg boots, according to Lee. His fingernails were also painted.

Lee said police initially thought they knew who the suspect was but bank employees did not identify anyone in a photo lineup. The suspect is not believed to be involved in any previous bank robberies.

"It's definitely a whodunnit," Lee said.

FBI spokeswoman Laura Eimiller told the Pasadena Star-News that a driver was waiting for the suspect and drove him away in a late-model Chrysler PT Cruiser.

Eimiller told the newspaper that police did not believe the robber's anthrax claims to be "a credible threat."
