NEWARK, N.J. (AP) — Authorities say a New York City man who had a knife in his pocket jumped over a barrier and ran onto the tarmac at Newark Liberty International Airport before being tackled by a police officer.

Thirty-nine-year Xiang Xun Shao of Manhattan was charged with defiant trespass and a weapons offense following Saturday night’s incident at Newark Liberty.

He was later taken to a nearby hospital, where he was undergoing a psychiatric evaluation.

A spokeswoman for the Port Authority of New York and New Jersey, which runs the airport, said Shao was initially seen walking around near a gate where vehicles access the tarmac area. He then jumped over a retractable metal barrier and briefly ran onto the tarmac before being caught near Terminal C.

No planes were delayed as a result of the incident.
