Sussex police made two arrests late on Friday in connection to the disruption and urged the public and passengers around the airport to be vigilant.

The airport had just endured a 36-hour shutdown over a drone the day before. The shutdown was travel chaos for more than 100,000 holiday travellers who were expected to fly out of or into the airport.

The 36-hour closure also affected Canadian travellers. WestJet Airlines said one of its flights from Toronto to Gatwick was diverted to Glasgow on Wednesday, and another flight, from Gatwick to Toronto, was cancelled on Thursday.

The airport, which is south of London, is Britain’s second-busiest by passenger numbers.
