Gatwick Airport, England (CNN) A man and a woman have been arrested on suspicion of "the criminal use of drones" at Gatwick following several days of disruption at Britain's second busiest airport.

The 47-year-old man and 54-year-old woman were arrested in Crawley -- the closest major town to the airport -- late Friday evening, police said, on suspicion of disrupting civil aviation services "to endanger or likely to endanger safety of operations or persons."

The suspects, both from Crawley, remained in custody as of 11 a.m. (6 a.m. ET) on Saturday.

"Our investigations are still ongoing, and our activities at the airport continue to build resilience to detect and mitigate further incursions from drones, by deploying a range of tactics," Sussex Police Superintendent James Collis said.

"The arrests we have made are a result of our determination to keep the public safe from harm, every line of inquiry will remain open to us until we are confident that we have mitigated further threats to the safety of passengers."
