An arrest has been made in the celebrity hacking probe which included Scarlett Johansson, Christina Aguilera and other stars.

Christopher Chaney of Jacksonville, FL was indicted on 25 counts of identity theft and hacking as part of a year-long investigation called Operation Hackerazzi.

According to a federal grand jury, Chaney gained illegal access to the e-mail accounts of more than 50 people. Other victims include actresses Mila Kunis and Reese Witherspoon.

TMZ.com reported that hackers stole nude pictures of Johansson from her cellphone and posted them on a website earlier this year.
