The invasion occurred around 3:00 a.m. at the facility located on the 200 block of Whiskey Mill Road in East Greenwich, Gloucester County.
Police say the robbery began when one of the group home's employees was taking out the trash. That's when three armed men entered the home and tied up and duct taped four employees.
The suspects then made off with an unknown amount of items and property, authorities say.
There were no injuries.
Investigators are working on getting descriptions of the robbers.
