Private images of Maisie Williams and her friends leaked on social media were “not explicit”, a spokesman for Game Of Thrones star has said.

Reports emerged on Wednesday that the 19-year-old had a social media account hacked and a “topless” picture of her was shared.

Other pictures reportedly showed her friends getting undressed by the sea in Japan, where she has recently been campaigning for the protection of dolphins in captivity.

A spokesman for the star said: “The images online were shared from Maisie’s personal social media account.

“The images are not explicit in nature, but pictures of Maisie and close friends at a spa at a recent visit in Japan.”

Her representative did not confirm whether any charges have been made.

Maisie, who has played Arya Stark in the HBO fantasy series for the last five years, recently appeared in a new trailer released for the show’s seventh season.

She also featured in four episodes of Doctor Who last year and the Channel 4 film, Cyberbully.
