Authorities say a New York City man who had a knife in his pocket jumped over a barrier and ran onto the tarmac at a northern New Jersey airport before being tackled by a police officer.
Xiang Xun Shao, of Manhattan, was charged with defiant trespass and a weapons offense following Saturday night's incident at Newark Liberty International Airport.
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.
