Banks in Knox, Whitley, and McCreary County have been robbed by a man police are now calling....the "Bad Hair Bandit."
Police say he's robbed at least six banks in Kentucky and Tennessee.
FBI investigators are stepping up their efforts by offering a reward for information leading to an arrest in this case.
In each robbery, the suspect has been a man wearing a woman's wig and sunglasses.
The string of robberies began in June.
The most recent took place just last week.
