A "sickness bug" on board a flight from Spain caused passengers to "drop like flies" and triggered an emergency response, it has emerged.

The Jet2 flight was surrounded by emergency vehicles on the runway at Leeds Bradford Airport at 9.45pm on Saturday after reports that four people were unwell on-board.

Other passengers were kept on board for more than an hour whilst the authorities made sure that the sickness was not contagious.

The four had been "violently sick" to the point where one "passed out", other passengers said.

Passenger Nicola Titley wrote on Facebook: "People dropping like flies on the plane... never seen so many emergency vehicles surround a plane so fast after landing."

Ms Titley, who praised the response of the cabin crew, said that the other passengers were checked for signs of illness but it had been suggested all four people who fell ill may have been staying in the same hotel.
