Mehmet Eymür, a leading official of the Turkish National Intelligence Organization (MİT) disclosed that he was the first person to employ Alaattin Çakıcı for covered operations of the MİT. Yavuz Ataç, an operations official, confirmed that he was introduced to Alaattin Çakıcı two months later he joined the MİT in May 1987 as the manager of the security department. Ataç says "Çakıcı has been a fugitive, sought for six or seven crimes at the time he first met him". According to Ataç, Çakıcı was assigned to operations outside of Turkey.
As determined by the security forces, Çakıcı was in 1995 on the assassination list of Dev Sol, a Marxist-Leninist organization.
In 1991, Çakıcı made his second marriage with Nuriye Uğur Kılıç, the daughter of Dündar Kılıç, a mob boss of the Turkish underworld nicknamed the "godfather of godfathers" (Turkish: Babaların Babası). However, he and his father-in-law fell out following the chain of incidents known as the "Engin Civan Scandal". In November 1994, the couple divorced. He contracted killing of his ex-wife Uğur Kılıç and his ex-henchman Nurullah Tevfik Ağansoy. On 20 January 1995, she was shot dead with three bullets fired by the hitman Abdurrahman Keskin in front of her son Onur in Uludağ, a ski-resort in Bursa. It was on Çakıcı's birthday.
Çakıcı contracted the assassination of Cavit Çağlar, a wealthy businessman from Bursa and a high-level politician and government minister, and Mehmet Üstünkaya, former president of Beşiktaş JK, in relation with the incidents known as the "Türkbank scandal", in connection with the privatization of Türk Ticaret Bankası to Korkmaz Yiğit. The plot was uncovered by the police at the preparation stage.
Çakıcı fled abroad in 1992 with the help of a false passport. It was determined that he toured in Belgium, USA, Italy, South Africa, France, Brazil, Singapore and Japan. He is held responsible for the murder of 41 people.
Informed by the Turkish police, French police apprehended him on 17 August 1998 in a hotel in Nice, France together with his bodyguard Murat Güler and his courier Aslı Fatoş Ural, daughter of composer Selçuk Ural. He had been carrying a fake diplomatic passport (red passport) on the name of "Nedim Caner" and US$17,000 cash with him.
His capture revealed his connections not only to the intelligence service people but also to high-level politicians. Recording tapes published after his capture in 1998 in France led to the resignation of the government minister from the Motherland Party (ANAP) Eyüp Aşık, who was accused of warning Çakıcı to flee. Meral Akşener, minister of interior from the True Path Party (DYP), MİT agent Yavuz Ataç and businessman Erol Evcil were also accused of the same allegation. After 16 months of isolated incarceration in France, he was returned to Turkey of his own will on 14 December 1999. He was imprisoned in Kartal Prison in Istanbul. Following controversies with rival gang member inmates, he was transferred to the maximum security Kandıra Prison in Kocaeli.
In June 2000 he was sentenced to five years for running a criminal gang.
Çakıcı was released from the prison on 1 December 2002. Although not allowed to leave Turkey and his passport confiscated, he fled from Antalya to Greece by sea as told by a group of people, including his nephew and Erol Evcil, who were apprehended by the police in Foça, Izmir. Çakıcı had obtained a passport with false identity and photograph from the police in Ümraniye, Istanbul.
Çakıcı stayed four-and-half months in Paris and Strasbourg in France as observed by the Turkish police. In order to visit Ali Çakıcı, his son from the first marriage, in a hospital in Graz, he drove to Austria changing three times his car underway. His intention was to pass later to Italy to join his sweetheart Aslı Fatoş Ural. Austrian police, informed by the Turkish police, apprehended Çakıcı on 14 July 2004 out of Graz. He had been carrying a Turkish special passport (green passport) issued on the name Faik Meral, a retired MİT agent, and its expiration extended from the police in İzmir. He had EUR 4,000 in cash with him. Visas in his passport showed that he traveled first to Russia and then entered Germany, where he stayed a while before going to France.
On 14 October 2004, Çakıcı was deported from Austria at the request of the Turkish Ministry of Justice. He was brought from Vienna to Istanbul in a commercial airliner escorted by five policemen. After trial, he was imprisoned in the maximum security prison in Tekirdağ.
