The investigation into alleged fraud in a 2010 nationwide civil-service recruitment exam in Turkey has revealed that the suspects have used wireless electronic devices to answer all questions correctly.According to reports, a complex plot was set up to ensure that a number of people affiliated with the Gülen Movement could receive high marks from the nationwide exam. Two groups were established to participate in the exam, where the first group would symbolically enter the classrooms where the exams took place to set up the electronic system necessary to transmit the answers to the questions. They left before the exam was over and allegedly used a Bluetooth device to communicate with the second group who wrote the exam. On May 26, the Turkish police detained 25 people in connection with the cheating scandal. The Public Personnel Selection Exam (KPSS) cheating scandal hit the headlines when it was discovered that numerous people affiliated with the Gülen Movement received full marks from the exam, although they had performed poorly in their previous attempts. The first wave of arrests came in late March in 14 provinces, including Ankara, Istanbul and İzmir, which resulted in the detention of 62 suspects, 30 of whom were later released.Police allegedly found evidence for the involvement of members of the Gülen Movement in the fraud.The suspects of the first operation also faced charges of being members of a criminal organization, forgery, illegal and harmful activity in public institutions, destroying criminal evidence and abuse of power.Police units launched the second wave of the KPSS cheating investigation in 28 provinces 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 is reportedly unknown.After a Gülen Movement-linked Twitter account named @FuatAvni released details of the pre-dawn raids on Sunday night, many of the suspects reportedly left their homes with some leaving the country in order to escape arrest. Similar tipoffs 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 the 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, for 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.Members of the Gülen Movement have allegedly infiltrated state institutions with a supposed aim of bringing down the elected government and taking over the state. The network is run by Fethullah Gülen who lives in self-imposed exile in Pennsylvania.
