SWAT teams surrounded the building at 451 Frelinghuysen Avenue on Friday afternoon. It is listed as an address of several manufacturing and shipping companies, and is about a block away from the Newark-Liberty International Airport transit station.
Police was called in around 1 p.m., after reports of a “person with a gun” inside the building.
Two people were evacuated from the roof by police, WABC reported, noting that they were the new owners of the building who were apparently confronted by a squatter armed with a shotgun.
The drama unfolded mere minutes away from the Newark Liberty International Airport (EWR). A major hub for United Airlines, Newark is the second-busiest airport in the New York City area, serving 37.5 million passengers in 2015.
