( CNN ) -- Italian police descended on the national team 's Euro 2012 training base Monday to speak to Zenit St Petersburg defender Domenico Criscito as part of a wide-ranging investigation into match fixing . The 25-year-old , formerly of Genoa , was questioned by officials probing gambling markets linked to fixing results of matches in the Italian top flight . A total of 19 people were arrested in the ongoing investigation by magistrates in Cremona , 11 of them players in Italy 's top division . Juventus coach Antonio Conte , who led the club to the Serie A title last season , was spoken to by police , while Lazio 's captain Stefano Mauri was arrested . Juventus defiant in match-fix controversy . As a result of the dawn raid on Italy 's training camp at Coverciano , near Florence , Criscito decided to withdraw from the forthcoming Euro 2012 tournament in Poland and Ukraine . Italian Football Federation ( FIGC ) vice-president Demetrio Albertini said Criscito was hugely disappointed to miss out but that he quit in order to protect the rest of the squad . `` Criscito decided not to join Italy at the Euros . The tournament is no longer his priority , he wants to get in touch with the prosecutors as soon as possible to clear his position , '' Albertini said . `` We are with him , we believe in his innocence : until no evidence is proved , he should be considered innocent . '' Prosecutors said the left-back was seen in a restaurant with match fixing suspects during his time at Genoa but the player has also protested his innocence . Criscito 's agent Andrea D'Amico said : `` Criscito is calm but very surprised . He just joined a dinner with fans , a meeting asked by fans after the derby Genoa lost to Sampdoria in 2011 . `` He did n't know any of the ultras involved . He ca n't understand how he could be connected to this story . As soon as possible he will ask prosecutors to be interrogated . '' Roberto Di Martino , chief prosecutor in the case , told a press conference the police 's swoop on Italy 's base was solely related to Criscito . `` We should n't place too much emphasis on the blitz at Coverciano , '' he said . `` It is a problem that concerns only Criscito and not other players in the national team at the moment . `` Also we should n't place too much emphasis on this anyway , the notification of an impending investigation is a tool we have , but not a guilty judgment . There 's been no action taken against Criscito travelling , he can play at the Euros easily . '' Police said Juve manager Conte was being quizzed in relation to sporting fraud accusations relating to a match played by Siena , the club he used to coach . Conte 's lawyer said his client was completely innocent . Siena 's president , Massimo Mezzaroma , has also been placed under investigation . Di Martino added : `` There are seven , eight games being looked at and there have been statements that make us think they were manipulated . The searches involved players , coaches and directors of the club , including Conte and Mezzaroma . '' Di Martino also revealed the investigation was spreading beyond Italian borders , with five people arrested in Hungary . `` We have evidence that this Hungarian gang worked to fix in Serie A 2010-11 the games between Bari and Sampdoria , Lecce and Lazio and some others . `` We have different evidence of their presence in Italy and of their contacts with people from Singapore , where the money is coming from . '' The arrests are the latest in a long running saga that has cast a shadow over Italian football . In 2006 the Calciopoli match fixing scandal saw Juventus relegated to the second tier and stripped of two league titles . Seventeen people were arrested in a similar swoop last year , the most high-profile of which was Atalanta captain Cristiano Doni . He was subsequently banned from the game for three years . Giovanni Trapattoni , who coached the Italian national team for four years , said the latest twist represented `` devastating news . '' Trapattoni , who now coaches Ireland , said : `` What could be the Italian team 's reaction ? On one side it is clear that news like this can bring people down , but it could also push them to show the clean face of football . `` As someone who has been abroad for years it 's a pity that these things cast a dark shadow over our football .
