Following a series of police raids on the homes of numerous businessmen and the sons of four cabinet ministers as part of a government corruption scandal, the serving İstanbul General Director of Security who had ordered the operations, Hüseyin Çapkın, was removed from his post. In his government's defence, Prime Minister Recep Tayyip Erdoğan had accused the perpetrators of the anti-corruption operation to be sympathisers of the Gülen Movement and would be removed from their positions. After the controversial removal of Çapkın from office, Altınok was appointed as the new General Director of Security for İstanbul.
While serving as the İstanbul General Director of Security, a recording of a phone call between Altınok and the then-Undersecretary to the Interior Ministry Efkan Ala was leaked on the Internet, allegedly by the Gülen Movement. In the alleged phone call, Altınok could be heard saying that 'they would violently crush the heads of any dissident'. The released recordings, which targeted numerous government ministers and supporters, were dismissed as fakes by the then-Prime Minister Recep Tayyip Erdoğan.
Minister of the Interior
After the June 2015 general election resulted in a hung parliament, unsuccessful coalition negotiations raised speculation over whether President Recep Tayyip Erdoğan would call an early election in the event that AKP leader Ahmet Davutoğlu was unable to form a government within the given constitutional time of 45 days. As required by the 114th article of the Constitution of Turkey, the calling of a snap general election by the President necessitates the forming of an interim election government, in which all parties represented in Parliament are given a certain number of ministers according to how many MPs they have. If a party refused to send ministers to the interim cabinet, then independents must take their place. When going into an election, the Constitution requires that the partisan ministers responsible for the Interior, for Justice and for Transport to resign from their positions and to be replaced by independent civil servants three months before polling day. As a result, the Interior Ministry was already administered by the independent former Undersecretary, Sebahattin Öztürk, since 7 March 2015. When the interim cabinet was announced, Altınok was announced as the new independent Minister of the Interior on 28 August 2015. He is known for being close to the former AKP Interior MinisterEfkan Âlâ, who resigned as required by the Constitution on 7 March 2015.
