A parliamentary committee is examining an additional 200 pages assembled by the Milan prosecutors investigating Premier Silvio Berlusconi on suspicion he paid for sex with a 17-year-old Moroccan girl.
The committee has to decide whether to allow a search of some of Berlusconi's properties. A decision might come Thursday.
The new documents reportedly include wiretaps of conversations between young women who went to parties at the Italian leader's villa, alleged evidence of payments to them and reports from police searches conducted earlier this month at some of the women's homes.
The prosecutors had already sent the parliamentary committee almost 400 pages of documents. Berlusconi denies wrongdoing, and has called the allegations "outrageous."
