Serbian soccer player Almir Gegic is being questioned in Cremona on Thursday for his alleged involvement in a widespread match-fixing scandal.
The midfielder's hearing is likely to carry over until Friday.
After more than a year on the run, Gegic surrendered Monday.
Gegic was brought to a jail in Cremona, where prosecutor Roberto Di Martino is holding the inquiry. More than 50 people have been arrested so far and over 100 are under investigation.
Gegic allegedly was a link between the fixing ring's base in Asia and Italian players. He was charged with criminal association and sports fraud.
The Cremona case, along with related inquiries in Bari and Naples, has resulted in many clubs being docked points during the past two seasons. Several coaches and players have been banned.
