NEWARK (WABC) -- Terminal C at Newark International Airport is locked down after a man walked through the exit at a check point.

According to the TSA, the man went from the "public" side to the "sterile" side.

They are reviewing video cameras. Port Authority police are looking for the individual right now.

They are not sure if he was once on the sterile side and went back or if he never went through screening.
