The item was found at Terminal A on level 3, according to Port Authority police spokesman Joe Pentangelo. Authorities initially cleared the area around 4:30 p.m., but later said the package was found not to be a threat and reopened the terminal.
“Package has been cleared by authorities at Terminal A at Newark Liberty Airport. Passengers should expect some residual delays,” the Port Authority said on Twitter.
The Port Authority police union said the item was a pressure cooker, but it did not pose a threat. Witnesses posted photos on social media showing the item near a trash bin in front of the terminal.
Officials did not have additional details Saturday.
