A French national has been charged with raping a British backpacker on the popular holiday island of Koh Tao, police said on Tuesday.
Police said his arrest follows a complaint by an 18-year-old woman, whose name was withheld, that she was drugged and raped by a French tourist on April 4.
Police identified the suspect as 26-year-old French national Yohan Michael Tunka Buaga. He was arrested on Saturday and charged with rape on Monday and is being held on the nearby island of Koh Samui.
"The suspect has admitted to having sexual intercourse with the victim, but he said that it was consensual and not rape," Pol Lt Col Piyapong Boonkaew of Koh Tao police told Reuters.
"We are now investigating the case and waiting for forensic examination," he said.
The holiday island made headlines in 2014 when the bodies of British backpackers Hannah Witheridge, 23, and David Miller, 24, were found on a beach. They had been bludgeoned to death.
Two Myanmar migrant workers, Zaw Lin and Win Zaw Tun, were found guilty in 2015 of killing the pair.
