English actress Maisie Williams, who is popular for playing the feisty Arya Stark in Game Of Thrones, seems to be the latest celebrity to have fallen victim to internet hackers. Concerns that her social media account may have been hacked surfaced after a photo appearing to feature a topless Williams began circulating on social media.

According to reports, one of the private pictures shows the back of the 19-year-old actress sitting on a rock wearing just black bikini bottoms as she looks over her shoulder. Another photograph features Williams with her female friends getting undressed near the sea.

If a report by DigitalSpy is to be believed, the photographs that have been doing the rounds over the weekend on link-sharing sites are believed to have been leaked from a private Facebook account.

In addition to this, the entertainment website also speculated that the snaps were from Williams' recent visit to Japan.

After one of the pictures surfaced on Instagram, fans urged that the photo be deleted as it was allegedly stolen from her private account. "Pls delete this picture, it was stolen from Maisie's private account," wrote one user.

The Cyberbully actress is reportedly on a tour of the island nation as an ambassador for the Dolphin project. During her visit, Williams is said to have visited the Japanese town of Taiji to campaign against the capturing and killing of dolphins. She has been quite active on social media as well, as she hopes to use her four million followers on Instgram and more than 1.5 million on Twitter to put words into action.

Sharing a photo of the island on the picture-sharing site, Williams wrote, "A pod of bottlenose dolphins have been driven into the killing cove. These dolphins are highly valuable to the hunters, some of these dolphins may end up in captivity for a high price. We have to end the cycle... Take the pledge. Spread the word".

With this alleged hack, Williams joins the long list of A-listers such as actresses Jennifer Lawrence, Kisten Dunst and Kaley Cuoco, who fell victim to picture leaks after their iCloud accounts were hacked in 2014.

IBTimes UK has contacted Williams' representatives for a comment and is awaiting response.
