When a woman breached a security checkpoint at Newark Liberty International airport in New Jersey this weekend, police evacuated the terminal out of caution, sparking chaos as passengers ran for the exits.

A spokesperson with the Port Authority of New York and New Jersey told PIX11 News the woman breached a security checkpoint in Terminal C around 10:20 a.m. on Sunday.

The police evacuated the terminal and swept the area for any possible threats, before resuming regular operations. 

Newark airport is located 15 miles southwest of Manhattan. Owned by the city of Newark, it is operated by the Port Authority of New York and New Jersey. Together, Newark, LaGuardia and John F. Kennedy airports make up the largest airport system in the country, the busiest in the world by flight operations, and second busiest by passenger traffic.
