Mauri was one of 19 people implicated in the investigation into alleged match-fixing in the domestic game, as police swooped in dawn raids on a number of addresses up and down the country, according to Italy's domestic Ansa news agency.

The players are suspected of having received money to fix matches for betting syndicates, whose head is believed to be based in Singapore.

National team full-back Criscito's room was searched at Italy's Euro 2012 camp just outside Florence, while police also searched the home of Antonio Conte, the coach of Serie A champions Juventus.

The public prosecutor in Cremona, Stefano Di Martino, said three Serie A matches -- Bari-Sampdoria, Lecce-Lazio and Lazio-Genoa -- were being investigated as well as seven or eight matches involving Siena last season when they were in Serie B.

Di Martino said two million euros ($2.5 million) was won on the Lecce-Lazio match and 600,000 euros was used to bribe players.

The raids come less than two weeks before the European Championships begin in Poland and Ukraine, with Criscito usually Italy coach Cesare Prandelli's first choice left back.

Prandelli was due to announce his final 23-man tournament squad on Monday before a warm-up match against Luxembourg in Parma on Tuesday.

Di Martino, however, said Criscito could calmly go to the Euros, as he was merely issued a notice of indictment, meaning he is helping investigators and has not been charged with any crime.

The player's agent, Andrea D'Amico, added that Criscito, who did not train with his team-mates on Monday morning, was calm and claims to have simply met with his ex-club's fans following a derby defeat to Sampdoria.

In May last year, Criscito, who now plays for Zenit St Petersburg in Russia, is alleged to have met with then-Genoa team-mate Giuseppe Sculli, two heads of the club's ultra fans and a Bosnian with a criminal record in a restaurant in the city.

Cremona prosecutors asked for an arrest warrant for Sculli, 31, but that was rejected by the preliminary investigation judge.

Conte, who guided Juve to their first Serie A title since 2003, is being investigated over his time as coach of Siena in Serie B last season.

"Conte has reacted as someone completely removed and strongly determined to show he has nothing to do with these accusations," said Conte's agent, Antonio De Rencis.

Of the 19 people targeted by the raids, 14 were arrested, three placed under house arrest and two ordered to present themselves to a police station.

Eleven are either current or former players, mostly from Italy's top four divisions.

As well as 32-year-old Mauri, former Genoa and Fiorentina midfielder Omar Milanetto, 36 who is now with Padova in Serie B, was arrested. Chievo captain Sergio Pellissier also had his home searched.

Five Hungarians, two who were arrested and three more already behind bars, are believed to have had contacts with a group of Zingari -- Gypsies in Italian -- and the chiefs in Singapore to manipulate Italian matches.

The fall-out to the so-called Calcioscommesse -- football betting -- investigation has been felt since last year with several high-profile names implicated.

Italy has a history of match-fixing scandals, although they have tended to precede sporting success.

The 1980 Totonero scandal saw AC Milan and Lazio relegated to Serie B while star striker Paolo Rossi was banned for two years. He came back just in time to be Italy's hero in their 1982 World Cup victory.

In 2006, Juve were relegated and stripped of their 2005 and 2006 titles for interfering with the referees' commission. Just over a month later, Italy won their fourth World Cup.
