( CNN ) -- Turkish police have swooped to detain 46 people as part of a widespread investigation into match-fixing in European football . Former Turkey international players Arif Erdem and Fatih Akyel were among those held , along with Bosnia goalkeeper Kenan Hasagic , Turkey 's Hurriyet Daily News reported on Wednesday . Erdem is assistant coach of the Istanbul Municipality team , whose 3-1 victory in a Turkish Super League match against Genclerbirligi in May 2009 is under investigation by the Turkish Football Federation . The game had also come under suspicion from German prosecutors who launched a probe into match-fixing last year . Goalkeeper Recep Ozturk , who then played for Genclerbirligi but is now at Konyaspor , has also been detained after being accused of betting €30,000 ( $ 40,000 ) against his own team , Hurriyet . Erdem played 60 times for his country and had a long career at leading club Galatasaray before retiring in 2005 , and along with Akyel helped Turkey finish third at the 2002 World Cup . Hasagic has played for Bosnia Herzegovina in 29 international matches . The Turkish federation said its investigation was separate to the Bochum probe , which has targeted more than 200 matches in 11 countries . `` The federation filed a complaint to the Sariyer Prosecutor 's office on August 4 , 2009 , regarding information it has on match-fixing doubts in three games , '' it said on its official Web site . `` The investigation by the Bochum prosecutors was made public in November , and the information and documents obtained from Bochum prosecutors and the UEFA have been shared with the Sariyer Prosecutor 's Office . '' Turkish police said the raids took place all across the country , according to the state-run Anatolia News Agency . `` As part of the investigation , 46 people have been detained from 26 different provinces . We are targeting 53 suspects , '' Istanbul police chief Huseyin Capkin said . The arrests came just three days after Swiss club Sion told prosecutors that last week 's 2-0 defeat by Grasshoppers Zurich appeared to have been targeted by match-fixers . The club said on its Web site that information in betting shops before the game indicated that the result would be manipulated . European football 's governing body UEFA announced last week that Ukrainian referee Oleh Orekhov had been banned for life based on information from German police 's investigations into match-fixing and corruption . In China , which has also been trying to stamp out match-fixing , police arrested three referees this month . One of them , Lu Jun , officiated in two World Cup matches in 2002 but has been accused of accepting bribes before his retirement in 2005 . Two clubs in China 's top league have been relegated in relation to the investigations , which also saw the country 's football head Nan Yong lose his job .
