Johansson among victims of phone hackers

FBI agents are today investigating a series of computer hacking attacks on celebrities.

FBI spokeswoman Laura Eimiller said dozens of celebrities had been targeted by the hackers, who stole personal information from email and other computer accounts.

She declined to provide further details, but several websites including TMZ have identified one of the victims as Scarlett Johansson.

Nude pictures, which appear to have been taken with a mirror by the actress herself, were leaked online yesterday.

The 26-year-old actress' publicist has so far refused to comment on the probe or reveal if the images – which also feature one showing a tattoo the screen beauty has been pictured displaying before - are genuine, but her representatives contacted the FBI because they believe a criminal act has taken place, according to TMZ.com.

'Friends with Benefits' co-stars Mila Kunis and Justin Timberlake are also thought to be the victims of hackers after photos of the pair, including a shirtless snap of the 'The Social Network' actor, were leaked.

Laura Eimiller, of the FBI office in Los Angeles, explained: "The FBI is investigating the person or groups responsible for a series of computer intrusions involving high-profile figures."

Eimiller did not name any of the alleged victims "due to the pending nature of our investigation".

Earlier this year, a group of hackers were reported to have stolen nude photos from the phones of up to 50 celebrities, including Jessica Alba, Christina Aguilera, Miley Cyrus and Vanessa Hudgens.

Vanessa met with FBI agents in March to discuss hacking of her emails.
