Following completion of an interrogation by Prosecutor Yücel Erkman on Thursday, 42 of 44 Gülen Movement-affiliated suspects were referred to an Ankara court for arrest. The suspects are accused of being involved in the 2010 Public Personnel Selection Exam (KPSS) cheating scandal.

Police units launched the second wave of the KPSS cheating investigation in 28 provinces across the country and took 35 of 78 suspects into custody on Monday morning. Nine other suspects were taken into custody a day later and the whereabouts of 33 others are reportedly unknown.

After a Gülen Movement-linked Twitter account released details of the pre-dawn raids on Sunday night, many of the suspects reportedly left their addresses with some leaving the country to escape arrest. Similar tip-offs were announced by anonymous Gülen Movement-affiliated Twitter accounts, hinting at the movement's deep infiltration in state institutions, mainly the judiciary, police department and media.

The operation was launched jointly by the Ankara Police Department's Anti-Smuggling and Organized Crime Bureau and Financial Crime Bureau, and was put into action to investigate the purported Gülen Movement-linked suspects' alleged involvement in mass cheating on the 2010 KPSS, in which Fethullah Gülen is the prime suspect. In the first wave of the operation, 32 out of 62 Gülen Movement-linked suspects were arrested on March 27.
