NEWARK, N.J. (CBS 2) — Remember the Rutgers student who ducked around a security checkpoint at Newark Liberty Airport in January and kissed his girlfriend? Turns out it was a very expensive kiss.

Haisong Jiang was arrested on January 8, days after the security breach that led to a busy terminal being shut down for hours, delaying or canceling about 200 flights around the world.

Jiang pleaded guilty to “defiant trespass” and was fined $3,000 on top of a $500 fine imposed by a Newark judge.

His lawyer, Eric Bruce, defended him as “simply a lovesick man who made a mistake.”
