The inquiry started following a denunciation from Lega Pro Prima Divisione club Cremonese, instigated by internal suspicions involving first team goalkeeper Marco Paoloni, who was sold to Benevento in January 2011.
[2] Some of the involved persons had already been questioned or condemned for similar charges: Cristiano Doni was acquitted in 2000, whereas Vincenzo Sommese (in 2007) and Stefano Bettarini (in 2005) were each disqualified for six months due to illegal betting.
[9] On 19 December 2011, a new police operation coordinated by the Magistrature of Cremona led to a number of high-profile arrests, including active and former footballers such as Cristiano Doni, Luigi Sartor, Alessandro Zamperini, Nicola Santoni, Carlo Gervasoni and Filippo Carobbio.
[16] The scandal then dramatically evolved a few months later: on 28 May 2012, a number of higher-profile players were involved, and the Cremone Magistrature went on to arrest Lazio vice-captain Stefano Mauri, former Genoa captain Omar Milanetto, Cristian Bertani, Paolo Acerbis, Matteo Gritti, Alessandro Pellicori, Ivan Tisci and Marco Turati, whereas José Joelson Inácio was put under house arrest and Kewullay Conteh and Francesco Ruopolo were forbidden to leave the country.
[17][18] More football figures were also put under investigation: among these, Juventus Serie A-winning head coach Antonio Conte (due to alleged failure to report attempted sporting fraud during his period as Siena manager), former Milan star Kakha Kaladze, Genoa striker Giuseppe Sculli (for whom the judge rejected an arrest request), Chievo striker Sergio Pellissier and Italian international Domenico Criscito who was training at Coverciano with the Azzurri team at the time, and was excluded from the UEFA Euro 2012 roster as a consequence.
