The FBI on Wednesday said it believes the bank robber nicknamed the "Bad Hair Bandit" has been arrested along with her alleged getaway driver.

Both identified themselves as Hayden residents, but law enforcement officials said the two appeared to have been living out of their car when they were arrested.

Cynthia Van Holland, 47, was arrested Monday by the Placer County sheriff's office, in California, for allegedly robbing Bank of the West, in Auburn, Calif.

She was taken into custody 12 miles from the bank along with Christopher Alonzo, 26, according to the FBI.

Dena Erwin, a spokeswoman for the sheriff's office, said they were on the run as Alonzo was wanted in Idaho.

The Bad Hair Bandit is responsible for up to 20 bank robberies in Washington, Oregon, Montana, and now California. The Bad Hair Bandit earned her nickname for the variety of wigs she wore during robberies.

Around 2:25 p.m. Monday, a female entered the Auburn bank and passed a note to a teller demanding money and stating that she was armed.

She was given an undetermined amount of money and left the bank.

Placer County deputies were able to arrest Van Holland and Alonzo when their vehicle and license plate matched a description given by a witness.

FBI spokeswoman Ayn Sandalo Dietrich, in Seattle, said investigators learned from witnesses that the robber typically waited in line as a customer before each robbery, then produced a note to a teller, in which she demanded cash and stated that she was armed.
