PARIS — Two men and a woman were questioned by the police on Thursday after being arrested in possession of two drones near the Belleville-sur-Loire nuclear power plant in central France, news agencies reported.

The arrests follow a wave of at least 14 illegal drone flights over French nuclear plants in recent weeks, which have raised concerns about the security of the country’s main source of electricity. However, the French news media reported that the three suspects — two men, ages 24 and 31, and a woman, 21 — did not appear to have any link to the mysterious drone flights. The woman was released Thursday.

Law enforcement officials told Agence France-Presse that the three did not have criminal records; they were suspected of having illegally flown two drones near the plant. Vincent Bonnefoy, a prosecutor from the area in central France, told reporters that the three were hobbyists who had been trying to film a remote-control boat in a lake near the plant. He said that one of the three flew a drone in the same area in October and made a film of the flight.

The newspaper Le Monde said they were arrested in a car in a restricted area about 650 feet from the plant.
