Italian prosecutors have confirmed that Prime Minister Silvio Berlusconi is under investigation in a prostitution case involving a then-underage Moroccan girl.
Italian media said investigators were also examining whether Berlusconi exerted improper pressure on police to have the girl released after she was detained over theft allegations.
The case of Karima El Mahroug became public months ago, when it emerged that 74-year-old Berlusconi had asked police to release the girl, who had previously been in his villa.
Berlusconi has said he is being unfairly targeted by politically motivated magistrates.
