Police have questioned and released the man suspected of breaching a secured part of Newark Airport and shutting it down last Sunday. Surveillance video showed the man, identified as 28-year-old Haison Jiang of Piscataway, waiting at the exit where passengers arriving from planes leave the terminal before he meets up with an exiting woman and goes back into the terminal. They appear to be smiling and happy. The breach put the airport on lockdown for six hours, and thousands of passengers were stranded. Video shows the TSA agent walking away from his post for a minute before the man enters the secured area. Jiang faces a charge of defiant trespass.
