Passengers fill the terminal after a security breach shut down Terminal C at Newark Liberty International Airport in Newark, N.J., Sunday, Jan. 3, 2010.
Another security breach closed down a section of Newark Liberty International Airport for about an hour on busy Presidents Day.
The Transportation Security Administration says the X-ray detected what appeared to be wine bottles in a passenger's carry-on. He was referred to a secondary screening because of the ban on carrying more than 3 ounces of liquids.
TSA spokeswoman Ann Davis says screening was halted in Terminal A around 4:45 p.m. Monday because the man apparently walked away. Davis says he was never located and apparently boarded his flight.
The incident occurred more than a month after officials said a Rutgers graduate student from China entered a secure area to say goodbye to his girlfriend. The Jan. 3 incident shut down Newark's Terminal C for hours and delayed passengers worldwide.
