Amanda Knox, the American student who was cleared of killing her British flatmate Meredith Kercher, kept a diary of her private interviews in jail, which revealed a male guard's repeated questioning of intimate details about her sex life.
The 24-year-old arrived back to Seattle from Italy after being jailed for four years at Italy's La Capanne jail near Perugia - the city where fellow student Meredith, 21, was stabbed to death in 2007.
"I was scandalised when I realised he wanted to talk about sex. He was fixed on the topic of sex - who I'd done it with and how I liked it," the Sun quoted her as writing.
Knox, whose conviction was quashed on Monday night, revealed he often called her to an empty office at night for a "chit-chat".
"He accompanied me to almost all my medical visits - two times a day - and at night he called me up to the third floor in an empty office for a 'chit-chat'," she wrote.
"When I repeated to him that I knew nothing about Meredith's murder, he tried to talk to me about her - I told him always that she was my friend - or provoke me into talking about sex.
"I realise he was testing me to see if I reacted badly, to understand my personality (to be a murderer, as he supposed). He also wanted to know with whom I had gone to bed, probably to give the police other names of suspects," she added.
The guard admitted asking language student Knox privately about how many boyfriends she had, but he insisted "it was always her who started talking about sex."
