Fenerbahce captain Mert Hakan Yandas is one of the players arrested
A wide-ranging investigation into illegal gambling involving figures in Turkish football is under way with hundreds of players, club owners and referees under scrutiny.
A series of police raids have taken place, arrests have been made and more than 1,000 players have been suspended as the scope of the inquiry continues to grow.
Turkish Football Federation (TFF) president Ibrahim Haciosmanoglu said at a press conference this week he saw "a growing sense of panic" within Turkish football "as operations deepen".
Last month the TFF suspended 1,024 players from its professional leagues as part of an investigation into betting.
