Besiktas says it is returning the Turkish Cup to the country's soccer federation until its deputy chairman and coach are cleared of charges in a match-fixing probe.

Thursday's decision comes a day after a court charged Besiktas' deputy chairman Serdar Adali and coach Tayfur Havutcu along with three other suspects. Besiktas has become the latest club to be implicated in the growing scandal.

Prosecutors have charged about 30 people, including the president of league champion Fenerbahce, in corruption allegations involving 19 games.
