A Birmingham woman armed with a promise, or a threat, tried to rob a Forestdale bank Wednesday morning.

The holdup attempt happened just before 10 a.m. at Regions Bank in the 1300 block of Tomahawk Road in Forestdale. Jefferson County Chief Deputy Randy Christian said deputies responded to a report that a black female had entered the bank and handed the manager a note demanding money.

Deputies arrived on scene quickly and found the suspect still inside the bank. She was taken into custody and is currently being questioned by detectives.

Christian said information from the scene is that the would-be robber passed a note to the manager demanding $6,000 from the vault. The note read that, if the manager complied, he would be rewarded with a sexual favor. If he refused, she would claim that he had sexually assaulted her.

"I don't think I have ever heard of an attempt to rob a bank quite like this,'' Christian said. "Our deputies were on the scene very quickly and saved this employee from something. I'm not sure exactly what but we saved him from something."

The woman will be taken to the Jefferson County Jail to await formal charges.
