Two armed men forced three employees to the floor in a Milford Township, Bucks County, bank Saturday morning and fled with a "significant amount" of cash, according to the FBI.

The men were hiding in the bushes by the back door of First Savings Bank on Commerce Boulevard when the first employee arrived at 7:50 a.m., the FBI said. They forced her inside, and the other two employees came soon after.

The robbers ordered the employees to open the vault and go inside, where they were handcuffed. The men took cash from the vault and the teller drawers, placed it in a large black duffel bag, and fled in an unknown direction. The FBI does not release the exact amounts of money taken in bank robberies, but Special Agent J.J. Klaver said this heist netted more than the average, which is about $2,000.

The robbers wore dark, hooded sweatshirts, ski masks, and gloves, authorities said. Both carried small walkie-talkie radios, which they used to speak to a third person, possibly a woman, during the 30-minute robbery. Both carried semiautomatic pistols, one silver and one dark-colored.

One of the men was about 5-foot-8 with a medium to heavy build, wearing camouflage cargo pants and brown boots. The other was taller and thinner and wore blue jeans and black shoes. Anyone with information on the robbery is asked to call the FBI at 215-418-4000.
