A 20-year-old man has been charged with hacking into the Yahoo email account of US Republican vice-presidential candidate Sarah Palin.
News of the hack broke last month, and uncovered Palin's wrongful use of a private email account to conduct official governmental business.
David C Kernell, 20, was indicted by a federal grand jury in Knoxville, Tennessee, for intentionally accessing without authorisation the email account.
The charge alleges that in mid-September, Kernell, a resident of Knoxville, obtained unauthorised access to Governor Sarah Palin's personal email account by resetting the account password.
According to the indictment, after answering a series of security questions that allowed him to reset the password and gain access to the email account, Kernell allegedly read the contents of the account and made screenshots of the email directory, email content and other personal information.
Further, it is alleged, Kernell posted screenshots of the emails and other personal information on a public website. Kernell is also alleged to have posted the new email account password, thus providing access to the account by others.
If convicted of the charge, Kernell faces a maximum of five years in prison, a £150,000 fine and a three-year term of supervised release. A trial date has not been set.
"Cyber crime is the FBI's top criminal investigative priority. We would like to thank all of the internet service providers and others who partnered with us to bring this matter to a quick and successful resolution," said Richard Lambert, special agent in charge at the FBI Knoxville Field Division.
Kernell is the son of a senior Democrat legislator; he has pleaded innocent to the charges.
