VALENCIA ( — Investigators with the Los Angeles County Sheriff’s Department and the FBI Thursday sought the public’s help in learning the identity and whereabouts of a female bank robbery suspect dubbed the “Bombshell Bandit.”

The robber’s name is based on the bomb threat she made during a recent robbery in Valencia, coupled with what witnesses described as a glamorous disguise, including a wig and large sunglasses, FBI spokeswoman Laura Eimiller said.

During the robbery at Bank of the West, located at 27011 McBean Parkway, the woman passed a note demanding cash and in which she threatened that a bomb would detonate if the teller did not comply with her demands, Eimiller said.

She was also seen by witnesses casing additional area banks on the day of the robbery and was last seen leaving the Bank of the West on foot, Eimiller said.

Witnesses described the woman as wearing an auburn or brown wig but that her natural hair color appeared to be black, said Eimiller. She was described broadly in terms of ethnic background to include white, Hispanic, Indian or of Middle Eastern descent.

The woman is believed to be 20-25, 5-foot-3 and approximately 125 pounds, Eimiller said.

Anyone with information about the suspect is asked to contact investigators with the LASD or the FBI, or dial 911.
