A man arrested for breaching security at New York's Newark airport, sparking the closure of a busy terminal, was kissing his girlfriend goodbye.

Haisong Jiang, 28, a Chinese-born student, was arrested late on Friday night and will be charged with defiant trespass, the Port Authority said.

He is due in court next week and could face a fine of up to $500 (£312).

Flights were grounded and passengers evacuated from the secure side of the terminal after the incident.

A surveillance video shows a man in a light-coloured jacket slipping underneath a security cordon at the airport, shortly after being told by an official to move away.
