Moroccan born Karima El Mahroug was only 17 when Berlusconi paid her for sex and gave cash and jewellery in return, after attending one of his parties, it has been claimed, reports the Daily Mail.
The recently leaked statements have revealed that she told investigators, "Everyone was naked at the bunga bunga parties and when I was in the police station Silvio was scared."
Mahroug also told prosecutors she was convinced Berlusconi had sex with lingerie model Noemi Letizia, who was first linked to Berlusconi in 2009 when it emerged he had attended her 18th birthday party.
In her statement she said, "I have never been to the primer minister Berlusconi's Rome residence but I have been to Villa San Martino (his home at Arcore near Milan) that's where I met Noemi who was known as the apple of papi's (Berlusconi) eye.
"Noemi asked me how old I was and I said 24, she joked with me and said she was Silvio's preferred one. From other girls who were at the party I discovered that there was an intimate relationship of a sexual nature between them."
Mahroug also said bunga bunga is a phrase that has gripped Italy and the rest of the world since it first emerged late last year.
"That evening Berlusconi told me that bunga bunga was a harem and that he had copied the idea from his friend Gaddafi and it involved women getting undressed and then letting him have bodily pleasure.
"During bunga bunga all the girls were naked and I got the sensation they were all trying to play themselves up with sexual acts so they would be noticed by Berlusconi," she said. (ANI)
