The man accused of hacking into the personal e-mail account of Republican politician Sarah Palin in 2008 is to serve his year long sentence in a federal prison.
David Kernell, the 23-year old former University of Tennessee student, was sentenced to 366 days by a federal judge in November last year.
At the time, the judge had suggested that the sentence was to be served in a halfway house to reflect the "unique circumstances" of the case.
Kernell used publicly available information on Palin to answer the security questions for her Yahoo e-mail account.
He later leaked the contents of the e-mail, which indicated that the politician was using her personal account for official use.
According to the BBC, the US Bureau of Prisons (BOP) has decided to ignore the judge's suggestion and has instead sent Kernell to a minimum security federal prison in Ashland, Kentucky.
The BOP refused to give a reason for sending Kernell to the facility but Professor Robert Weisberg of Stanford University, California says: “The judge can give either incarceration or probation, but if it's incarceration the state gives power to the Bureau of Prisons to determine the nature of incarceration.”
