Two armed men

fled Talbot State Bank on Ga. Highway 138 with an undisclosed amount of

cash Tuesday afternoon after locking bank employees in the vault, according

to authorities.

The men, who

were still at large Thursday afternoon, were black males wearing masks,

said Maj. Bruce Jordan of the Fayette County Sheriff's Department. One

of the assailants had a "street sweeper" shotgun, an illegal

weapon with a large cylinder that holds 12 rounds, Jordan said. The other

suspect had a handgun, he added.

The "street

sweeper" shotgun could provide a break in the case. Jordan said investigators

are asking the person who sold the gun to step forward and contact the

Sheriff's Department at 770-461-6353.

The incident

was recorded by security cameras and the tape has been given to the Federal

Bureau of Investigation, which is conducting the joint investigation with

the Sheriff's Department, Jordan said.

A reward is

being offered for information leading to the identification of the men

responsible for this robbery, according to the FBI. Anyone with information

is asked to contact the sheriff's office or the FBI's Bank Robbery Squad

at 404-679-9000.

The FBI described

the two men as follows:

A black male,

dark complexion; 5'8" to 5'10" tall, 170-180 pounds in his late

20s or early 30s and wearing blue jeans, a dark sweat shirt with writing,

black gloves and a baseball cap.

A black male,

6'0" to 6'2" tall, 180-200 pounds in his late 20s or early 30s

and wearing blue jeans and a sweatshirt with writing and a baseball cap

with writing.

When the pair

entered the bank at 1:15 p.m., one suspect stood guard at the entrance

while the other ushered the employees into the bank's vault.

The money that

was taken came from the vault and not the cash drawers of tellers, Jordan

said. After the vault was looted, the employees were locked inside, Jordan

added.

One of the

employees had a key to the vault and was able to open the doors after

the suspects left, Jordan said.

The bank alarm

was not activated until after the employees escaped the vault, he added.

The pair left

the bank in a white Cadillac which they dumped in a secluded area several

blocks away and set on fire, Jordan said. After that, the pair got away

in a red Pontiac, according to a witness.

The witness

wasn't able to provide a better description of that car or the vehicle's

license plate, Jordan added.

"That's

the only description we've got," Jordan said.
