FBI investigating Montana bank robbery

BUTTE (AP) — The FBI is investigating whether a Montana bank robbery is related to at least 18 bank robberies in Washington and Oregon attributed to the "bad hair bandit."

A woman wearing a short, dark-haired wig robbed the Bank of Butte Thursday, getting away with an undisclosed amount of cash. The robber implied she had a gun.

Butte-Silver Bow County Sheriff John Walsh tells The Montana Standard (http://bit.ly/qbhTue) the FBI is looking into whether the bad hair bandit is involved. An FBI spokeswoman wouldn't comment.

The FBI's website says the bad hair bandit robs banks by passing a note to the teller and claiming that she has a gun. She wears a variety of unattractive wigs during the robberies.

A $10,000 reward is being offered for information leading to the bandit's conviction.
