A Transportation Security Administration agent was arrested at a New Jersey airport after authorities say she avoided a pre-flight screening and boarded a plane.

Authorities say Wanda Weems of Newark was detained Friday morning at Newark Liberty International Airport after she boarded a Continental Airlines flight bound for Houston.

Because neither Weems nor her luggage had been screened, the flight was delayed for more than an hour as each passenger was taken off the plane and screened again.

It's unclear why Weems avoided the screenings. Officials with the TSA and the Port Authority of New York and New Jersey, which operates the airport, didn't immediately return telephone calls seeking comment Saturday.
