A law enforcement source with knowledge of the investigation said that the team was filming for cable network CNBC, which is based in Englewood Cliffs. The TSA did not release the names of the people they said were arrested, and the Port Authority only said that it was investigating the incident.

A second source said the fake explosive device was a length of PVC pipe with wires sticking out from it. A bomb tech with the TSA determined that the device posed no threat, and that eight people were taken into custody.

A third source, who also asked to not be identified, said the crew was from the Endemol Shine Group, a Dutch production company that contracts with CNBC.
