Turkey's state-run news agency says there have been five more arrests in a growing match-fixing investigation, with Besiktas now implicated.

The Anatolia news said Thursday that Besiktas' deputy chairman Serdar Adali and coach Tayfur Havutcu were charged late Wednesday. Two players from Istanbul Buyuksehir Belediyespor were also arrested, raising the number of suspects in jail to more than 30.

Prosecutors have charged dozens of suspects, including the president of league champion Fenerbahce, over corruption allegations involving 19 games.

Besiktas finished fifth in the Turkish first league last season and also won the Turkish Cup.
