Police searched a United Airlines jet after a reportedly hallucinating passenger claimed there was a bomb on board

• Police met a United Airlines flight landing at Newark on Sunday after a passenger said that she thought there was a bomb on board.
• Police did not find a bomb, and believe that the passenger was hallucinating while under the influence of marijuana and Adderall.
• Video and photos from the scene show a swarm of police around the plane, with dogs checking offloaded luggage.

A United flight from Los Angeles to Newark was forced to stop short of the gate when it landed on Sunday, after a woman on the flight stood up and said that she thought there was a bomb on board.

The flight was met by police on the tarmac at Newark at 4:30 p.m., according to The Daily News. The incident set off a massive emergency response, with police cars and trucks surrounding the plane.

Images and videos posted by New Jersey's The Lakewood Scoop show police officers searching the plane with passengers still on board, and offloading each piece of luggage on the plane to be checked by canine units.

The Daily News, citing police sources, reports the passenger who talked about the bomb was believed to be under the influence of marijuana edibles and Adderall, and was believed to be hallucinating.

A United spokesperson confirmed to Business Insider that there was an "onboard medical emergency" during the flight, which led to the security scare.

"During the medical emergency onboard, the passenger made a remark which created a potential security concern," the spokesperson, Kimberly Gibbs, said in a statement. "The flight landed safely and the customer was transported to a local hospital."

A spokesperson for the Port Authority of New York and New Jersey, which operates the airport, did not reply to a request for comment.
