Prosecutors have appealed the acquittal of U.S. student Amanda Knox, who was on trial in Italy for the murder of her British roommate, Meredith Kercher, in the university town of Perugia about four years ago. Reuters

Amanda Knox who recently came home said that an Italian prison official sexually harassed her when she was in Italian prison for four years for the murder of her roommate, CBS news reported.

Peter Van Sant correspondent of 48 Hours Mystery interviewed Knox on The Early Show in which she revealed that a high-ranking Italian prison administrator ordered her into his cabin at night to talk about sex.

Knox on Oct. 4 returned home to Seattle, a day after she was acquitted of the murder of her British roommate Meredith Kercher in 2007.

Knox in a letter has described the sexual intimidation she experienced when she was in prison.

We learn about sexual harassment inside prison where an administrator would take her up to his office alone at night and say a number of inappropriate things to her, and that left Amanda terrified, Van Sant reported on The Early Show.

The show special on the Amanda Knox case was supposed to broadcast on Saturday evening but the report of Knox’s sexual harassment was leaked in advance.

The official was stuck on the topic of sex, with whom I'd done it, how I liked it, if I would like to do it with him, the letter said.

But when I realized that the official is obsessed with me to talk about sex I tried changing the topic several times, Knox added, the program's makers said in a report of the show before the broadcast.

The 24-year-old also wrote that: I realize that he was just testing me to see my reaction and to understand me personally. He wanted to get some information from me regarding the case but I did not get the seriousness of the situation.

Knox is an ex-student at the University of Washington. Both she and her former boyfriend, Raffaele Sollecito, were acquitted on Monday by an Italian appeals court.

Both were convicted of killing the 21-year-old Meredith Kercher, a British student who shared an apartment with Knox in Perugia.

Knox is thinking of completing her studies now that she is back at home.

However, it was not clear as to when the letter quoted by the TV show was written or to which prison official it referred to.
