Prosecutors: Silvio had sex with teen 13 times

Milan: Premier Silvio Berlusconi paid for sex with an under-age Moroccan teen 13 times at his villa near Milan, prosecutors have said in a document filed seeking indictments against three aides for allegedly soliciting prostitutes for the Italian leader.

The seven-page document, obtained by The Associated Press, alleges that the sex-fueled parties started with dinner, progressed to erotic dancing involving the premier and culminated with Berlusconi's choice of a sex partner, or partners.

Prosecutors have formally closed the investigation and are seeking indictments against the three aides, whom they accuse of identifying possible sex partners for Berlusconi and

informing them of payment and other compensation "that they would have received for their sexual availability."

The premier separately faces trial in Milan April 6 on charges of under-age prostitution and using his influence to cover it up.

A judge must now decide whether to indict the three aides, and start a separate trial. Berlusconi has denies all charges, and his lawyers have filed a complaint to Rome prosecutors, saying they feared a setup. Ruby also has denied having had sex with the premier, and says she has never acted as a prostitute.

Besides the Moroccan teen, Karima el-Mahroug, known by her nickname Ruby, the document identifies 32 other women whom the three aides involved in parties at Berlusconi's villa near Milan.

The prosecutors allege that aides have acted together in a criminal scheme to induce Ruby into prostitution. The document says that Ruby "committed sexual acts with Silvio Berlusconi, for payment in cash and other compensation, at his residence" outside of Milan on 13 occasions from Feb 14- May 2, 2010, the document says. Ruby, who has since turned 18, was 17 at the time.

According to the document, the evenings proceeded in three phases. Dinner was followed by erotic dancing, dubbed "bunga, bunga." During this phase, the women were either masked, did a striptease or erotic dance "touching each other mutually, touching or being touched in their intimate areas by Silvio Berlusconi."

The evening ended when Berlusconi chose "one or more girls with whom to spend a night of intimate relations, people who were paid sums of cash, or other compensation beyond what was given to the other participants."

"A third phase, at the end of the evening, consisted of the choice, on the part of Silvio Berlusconi, of one or more girls with whom to spend a night of intimate relations," the document said.
