Four men have been arrested, reports Italian paper Gazzetta dello Sport, though none of the quartet themselves are sportsmen.

The ‘calcioscommesse’ investigation is part of the Italian police’s operation against illegal betting in football, with the four men taken into custody believed to be alleged intermediaries between footballers and those placing bets.

Former Italy internationals Gattuso and Brocchi saw their houses raided as part of the operation and are now under investigation.Gazzetta also writes that authorities are taking a close look at a number of top-flight games involving Milan, Juventus and Inter.Those under the microscope are Milan-Lazio, Chievo-Milan [both February 2011], the March 2011 Milan-Bari game, Juve-Lazio [April 2012] and Palermo-Inter [April 2013].A press conference will be held later on Tuesday to give more details on the latest developments.Gattuso, 35, was sacked as Palermo manager in September. During a colourful playing career he represented Rangers and Milan, as well as winning 73 caps for the Italian national team.(uk.eurosport.yahoo.com)ANN.Az
