British police continue to search for leads into the Gatwick airport drone disruption, having come up empty-handed after a search of the Crawley home of a couple, the only people arrested so far, and who were subsequently released without charge.
"Over the last day or so we have been meticulously investigating their involvement. And I am satisfied now that they are no longer suspects in this investigation," said Sussex & Surrey police's Detective Chief Superintendent Jason Tingley.
Police have found a damaged drone on the ground near the airport's northern perimeter, and it has been taken away for forensic examination. Gatwick airport itself has offered a 50,000 pound reward to find out who was behind the attack.
Things are returning to normal for travellers, but many questions are still being asked about the preparedness of Britain's airport infrastructure to deal with such acts of sabotage.
