Hakan runs a talk-back Turkish community radio program. Last Tuesday, during a live show a caller claimed that Kemal Bosphorus, a prominent businessman, was involved with illegal gambling. The following week, Hakan repeated the allegations and said they were a pack of lies. Bosphorus is suing Hakan and the station for defamation.
