Police have arrested over 50 people in the country in relation to an investigation they are carrying out over alleged match-fixing as champions are caught up in new scandal
Fenerbahce president Aziz Yildirim and more than 50 other prominent football figures have been arrested in Turkey over match-fixing allegations.
Htspor.com reports organised crime units of the Istanbul police carried out the arrests early on Sunday morning and investigations will continue.
The Turkish champions' vice president Sekip Mosturoglu was also detained as part of the enquiries. Fenerbahce players Emmanuel Emenike and Sezer Ozturk have also come under the microscope as police continue their investigations.
Trabzonspor vice president Nevzat Sakar, players Umit Karan, Serdar Kulbilge and Serdar Calik were also arrested alongside many others.
More Super Lig clubs are reportedly involved in police investigations as well as a number of other coaches and players who have not been named.
Authorities have focussed their attention on Fenerbahce's final game of the season against Sivasspor which they won 4-3, a week after beating Ankaragucu 6-0.
Last month the Anatolia News Agency reported a disciplinary body for Turkish football concluded at least 17 games were fixed between 2008 and 2010.
