A federal building in Paterson, New Jersey was evacuated Wednesday afternoon when a toy aircraft was found on a deck, officials say.
An off-duty sheriff at 100 Hamilton Plaza noticed the aircraft on the first-floor deck of the building, which houses federal, state and county offices, according to the Paterson police director.
It wasn't a commercial drone, according to police. It didn't have the four propellers typically found on commercial drones -- so it wasn't capable of carrying anything, but it would have been able to record video.
No one saw the device in the air.
Federal officials, police, Office of Emergency Management and Passaic County Sheriff's Office are investigating the incident.
Police patrols were increased in the area as a precautionary measure.
