Mysterious wires found in the lavatory of a JFK-to- Madrid Delta flight might have been components of a bomb, law-enforcement sources said yesterday.

But investigators are still leaning toward an innocuous explanation of the discovery, said sources.

Officials first believed a woman who suffered a medical emergency when the wires were found was “supposed to be the decoy” to “the gentleman who [was] playing with the possible explosive device,” according to a radio transmission from the jet.

But the man and the woman were released after questioning.
