The FBI has a new addition to its "Wanted" list: the so-called "Ponytail Bandit," a 20-something blonde woman with her hair tied back who is suspected of robbing at least three banks in three states.

The unidentified woman — who is now on "America's Most Wanted" — is described as a slim, blonde Caucasian woman in her mid- to late-20s who wears a white or blue baseball cap with her ponytail coming out through the gap in the back. She has allegedly held up banks in Austin, Texas; Roseville, Calif.; and Lynwood, Wash.

"In each of the robberies, the woman entered the bank, verbally demanded money and then left the bank on foot," the FBI said in a press release.

The FBI has surveillance shots of the woman — whose name isn't yet known — carrying out the armed robberies. Each time, she has stood in the teller line slouched forward with her arms folded across her chest, according to the FBI.

Authorities began focusing on the suspect beginning May 7, when an Austin Wachovia Bank security camera caught her shoving money into her purse.

Robberies on May 23 at a Wells Fargo Bank in Roseville and on May 30 at a First Heritage Bank in Lynnwood are also believed to have been executed by the "Ponytail Bandit."

She is between 5'3" and 5'5" tall weighing 110 to 120 pounds and has shoulder-length blonde hair in a ponytail, which she has worn with a Longhorns or other baseball cap in all three hold-ups. She has no visible scars, marks or tattoos, the FBI reported.

The "Ponytail Bandit" is considered to be armed and dangerous.

Anyone with any information about her is asked to call the local FBI office or the nearest American embassy or consulate. They can also call the FBI in Sacramento at (916) 481-9110, the FBI in San Antonio at (210) 225-6741 or the FBI in Seattle at (206) 622-0460.
