TULSA, Oklahoma -- The FBI is offering a reward in a violent Tulsa bank robbery.

The agency will pay up to $10,000 for information leading to the identification and capture of three suspects in the takeover robbery of the Tulsa Municipal Employees Credit Union on September 16, 2011.

Police say three black males, all wearing ski masks, entered the Credit Union at 17th and Phoenix shortly after 11 a.m.

Police say all three robbers brandished firearms and threatened customers and employees during the robbery. One of the men fired a handgun into the teller's glass partition.

Tulsa Police say all three entered the vault area. After a few minutes in the vault, they ran out and left in a green Jeep Grand Cherokee.

Authorities say the suspect's violent action and reckless disregard for public safety was a factor in offering the reward for their capture.
