Two men disarmed and robbed an armored car employee Tuesday morning at a Bank of America in Lilburn.
An undisclosed amount of money was taken, police said.
The bank is located at the intersection of Hillcrest and Indian Trail Lilburn roads.
Lilburn police spokesman Sgt. Tyler Thomas said two masked men approached the armored car worker as he was loading an ATM at 7:30 a.m.
They forced the man to lie on the ground and took his pistol at gunpoint.
They then fled in a two-tone silver SUV, possibly a Mitsubishi Montero or Isuzu Rodeo, that may have been driven by a third suspect, Thomas said. The vehicle had a new-vehicle tag instead of a license plate, witnesses told police.
Following the armored car company's protocol, a second employee remained locked in the vehicle and sounded an alarm, Thomas said. Police arrived within two minutes.
Thomas said the bank had a surveillance camera, "but whether the video actually proved to be operational at the time, that's something the FBI will uncover in their investigation with bank security."
Gwinnett police helped canvass the area for the suspects, Thomas said. Police are asking anyone with information to call FBI Special Agent Stephen Emmett at 404-679-9000.
