Mahwah police say in a news release that the ATM employees had stopped at a business on Industrial Avenue when one of them placed the satchel on the front lawn as he moved items around in their vehicle.
They drove off, forgetting the bag.
Sometime after 11:15 am Monday, surveillance video shows a passenger in a white van grabbing the bag.
The van was seen in other video surveillance pulling into a nearby auto repair business and pilfering used tires.
Police say the ATM employees are cooperating with the investigation.
