David Cameron’s bodyguard has been taken off frontline duties after reportedly leaving his gun and former prime minister’s passport in an aeroplane toilet.
A passenger found the weapon and handed it to flight attendants on the British Airways flight.
It is believed that the gun 9mm Glock 17 pistol, which was left by one of Cameron’s close-protection officer who took off his holster while using the toilet.
The captain reassured passengers by telling them the protection officer was authorised to bring a gun on board.
It is apparent that the weapon was returned but a number of passengers objected to having the gun and then the gun was removed from the flight before take-off.
The incident caused the flight from New York to London to be delayed for over an hour.
In a statement, the Metropolitan Police said: “We are aware of the incident on a flight into the UK on 3 February and the officer involved has since been removed from operational duties.
“We are taking this matter extremely seriously and an internal investigation is taking place.”
British Airways said it followed Civil Aviation Authority rules which allow UK police to carry firearms on board in specific, controlled circumstances.
“Our crew dealt with the issue quickly before departure and the flight continued as normal,” the airline said.
Mr Cameron is entitled to continued security provided by the Met’s Specialist Protection unit as a former prime minister.
