In May 1998, the Grey Wolves were involved in two murders. On May 3, a group of Grey Wolves attacked two students in Bolu who were passing by the organization's building. Kenan Mak, one of the students, was killed. On May 5, a worker named Bilal Vural was killed in Istanbul's Şişli district, allegedly by the Grey Wolves. His family claimed that he was "brought several times to the Ülkü Ocakları building where ultranationalists forced him to become a member." They said that he was killed because he was a member of the pro-Kurdish People's Democracy Party (HADEP). As a result of these murders, Republican People's Party (CHP) Deputy Chairman Sinan Yerlikaya and the Freedom and Solidarity Party (ÖDP) requested that the Grey Wolves be banned by the authorities.
