Police have confirmed they have arrested a man suspected of discarding a package at the North Terminal of Gatwick airport.
Specialists have been called to the airport to investigate the item. The terminal has been evacuated, and some flights have been delayed.
Detective Superintendent Nick May said: “At this time, we are investigating the circumstances of the incident and it is too early to say what the item may be.
“However, given the events in Paris on Friday evening, there is heightened awareness around any such incident and it is best that we treat the matter in all seriousness.
“We are aware that there is concern about what has happened in France, but the general threat level remains the same and people should be aware as usual of anyone acting suspiciously.”
