Victoria Justice has vowed to discover the identity of a thief who stole her phone as personal photographs from the device have appeared online.

Snaps featuring the former child star, who rose to fame on Nickelodeon Tv shows Zoey 101 and Victorious, wearing a revealing bathing suit hit the web on Thursday (11Apr13), and Justice has now addressed the images, insisting they were taken from her cell phone.

In a series of posts on her page, she writes, "My phone was stolen & some1 (someone) leaked this. Wasn't meant 2 (sic) be 'sexy', I took it as a joke cuz (because) I look like an 80s aerobics instructor.

"Hacking & stealing is not cool. Respect peoples (sic) personal property... I would never post a picture of myself like that. I'm not taking this lightly & I will find out who stole my private property."
