A flight from JFK to Madrid, Spain, returned to New York Thursday night after air marshals discovered wires in the restroom and identified a passenger who appeared to be suspicious, sources told The Post.
A sweep of the jet back at JFK found no suspicious devices.
Delta Flight 126 took off at 8:10 p.m. and over the Atlantic turned back toward New York at 9:33 p.m.
Four marshals on board had discovered the wires hanging from the ceiling during a routine security sweep, police and aviation sources said.
Also, at one point, the pilot reported that a woman claimed to be ill. Back at JFK, she was taken away in an ambulance and placed under guard.
The plane taxied to a remote part of the airport and approximately 200 passengers on board were taken to a terminal to be questioned.
Reuters reports that a couple was taken into custody, the man being held was of Middle Eastern origin, while the woman was from Argentina. But it is not confirmed.
