An undercover agent with a fake explosive device in his pants was able to pass through two security checkpoints at the Newark, New Jersey airport, says a New York Post report. The incident, reported by the New York Post, occurred February 25 at the Newark Liberty International Airport as part of a training drill for the Transportation Security Administration.

The TSA would not confirm the report or the specific incident but said it regularly conducts covert testing.

According to the New York Post, the undercover agent was part of a four-person team drill last month at Newark, a major airport near New York City, the main target of the 2011 attack.

The "bomber" had a mock improvised explosive device in his pants and was able to pass through a detector and even a patdown by a TSA agent, allowing him to get to the airport gate and, in theory, board a plane, the newspaper said.
