The four Maldivian arrested in Sri Lanka on Saturday, for operating a drone over a high-security zone, have been released, RaajjeMV reported.While President Ibrahim Mohamed Solih arrived in Colombo on Sunday to attend the country’s Independence Day celebrations, RaajjeMV understands that they were released that night. They were arrested for flying the drone and video-graphing the area at the Katunayake, Bandaranaike International Airport, without the required approval. While the four are between the ages of 19 and 23, among them is a female.In Sri Lanka, a permit from the Civil Aviation Authority (CAA) is required before operating a drone. The permit can only be approved after the confirmation by the country’s defence ministry. A separate permit must be obtained to operate drone flights at night time. While they were to be produced to the Negombo Magistrate’s Court for a remand hearing on Sunday, it is not clear if they were released through court.
