Italian authorities arrested Lazio captain Stefano Mauri and more than a dozen others yesterday as part of a wide-ranging investigation into match-fixing in football.

Police also swept through the Italy national team training site near Florence as part of the operation.

Italy left back Domenico Criscito has also been implicated and was not considered for the European Championship next month, Italian football federation vice-president Demetrio Albertini said.

Police turned up at Italy's training base yesterday and warned the former Genoa player, now at Zenit St. Petersburg, that he was under investigation in a wide-ranging fix probe.

"It has been a decision agreed between (coach Cesare) Prandelli and the federation," Albertini told reporters.

"He (Criscito) was also sorry for the repercussions on the national team and on the dressing room. He explained some things to me and I believe his version and in his innocence."

Criscito, who prosecutors allege was photographed in a restaurant with match-fixing suspects while still a Genoa player, told reporters: "I have nothing to do with this. I was only out for dinner with some Genoa fans".

Serie A title-winning Juventus coach Antonio Conte is also under investigation over his time as Siena boss.

Italian soccer was last embroiled in a major match-fixing affair in 2006.
