Pair freed without charge in London airport drones probe

A man and a woman arrested over the drone disruption that brought Christmas getaway flights to a standstill at London's Gatwick Airport were released without charge on Sunday, police said.

A 47-year-old man and a 54-year-old woman from the town of Crawley, near Britain's second-busiest airport, were arrested on Saturday.

The police swooped after three days of disruption from Wednesday to Friday, affecting 140,000 passengers.

"Both people have fully co-operated with our enquiries and I am satisfied that they are no longer suspects in the drone incidents at Gatwick," Sussex Police detective chief superintendent Jason Tingley said in a statement.

Drones were sighted buzzing around the airfield more than 50 times, forcing the government to bring in specialist military resources to help counter the threat.

The dangers posed by drones include the possibility of a device smashing into a passenger plane or being sucked up into an engine where its highly flammable lithium battery could cause a catastrophe.

"Our inquiry continues at a pace to locate those responsible for the drone incursions, and we continue to actively follow lines of investigation," said Tingley.

"We ask for the public's continued support by reporting anything suspicious, contacting us with any information in relation to the drone incidents at Gatwick."
