New Jersey ? The man believed to have caused a security breach that resulted in major delays last weekend at Newark Liberty Airport when he took advantage of a guard’s absence to sneak past a checkpoint and walk arm-in-arm with a woman was arrested at his home, authorities said.

Haisong Jiang, 28, of Piscataway was taken into custody Friday night, the Port Authority of New York and New Jersey said. He was being held late Friday night at the airport by Port Authority police, who arrested him. The Port Authority said in a statement that Jiang is being charged with defiant trespass, and that the charge was determined in coordination with Essex County prosecutors and federal officials.

The breach led the TSA to shut down one of Newark Liberty International’s three terminals for six hours Sunday, stranding thousands of passengers and contributing to long delays.
