LOS ANGELES (AFP) - The FBI arrested a Florida computer hacker Wednesday for allegedly infiltrating the emails of Hollywood stars including Scarlett Johansson, naked pictures of whom appeared online last month. Christopher Chaney, 35, was arrested in Jacksonville, Florida as a result of an 11-month investigation into hacking of over 50 victims in the entertainment industry also including actresses Christina Aguilera and Mila Kunis. The suspect was brought before a court in Florida and was released on $10,000 bond to appear there again Friday, on conditions including that he have no access to a computer or other device with Internet access. He is expected to be transferred to face trial in Los Angeles, where he faces up to 121 years in prison if convicted on 26 indictments, including accessing and damaging computers, wire tapping and identify theft. Celebrity information is highly marketable, said Steven Martinez, head of the Federal Bureau of Investigations Los Angeles office, after what was dubbed Operation Hackerazzi.
