The women then followed the drone pilots back to port and alerted the police.
The young men then grew frightened and offered the women money "to eat in a nice restaurant" if they didn't report them, the newspaper said.
They then admitted that they had taken footage of the women sunbathing, but claimed the footage had been immediately deleted.
Once the police arrived, they mediated between the two sides and investigated whether the drone pilots had violated the young women's privacy and if they had the correct licence to operate the drone.
The increasing popularity of drones has led to fears they could be used by peeping toms and drug smugglers, as well as for other nefarious purposes.
The Register reported in April that complaints made to police in the UK about drones rose sharply from just a few hundred in 2014 to more than 3400 last year.
