The Chinese 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 has been arrested, authorities said.

Haisong Jiang, 28, of Piscataway was taken into custody at 7:30 p.m. Friday at his home, the Port Authority of New York and New Jersey said. He was questioned at the airport by Port Authority police, who arrested him, and released shortly after midnight.
