The man who is believed to have slipped into a secured area of Newark Liberty International Airport and to have caused a six-hour shutdown of a major terminal on Sunday has been arrested, Port Authority officials said on Friday night.

The man, Haisong Jiang, 28, was taken into custody at 7:30 p.m. at his home in Piscataway, N.J., according a statement from the Port Authority of New York and New Jersey. The agency said he would be charged with defiant trespass.

Mr. Jiang was held at the authority’s administration building at the airport until about midnight, when he was released on his own recognizance and issued a summons to appear in Newark Municipal Court next week, said Paul M. Loriquet, a spokesman for the Essex County district attorney’s office.
