Alparslan Arslan (born 1977 in Kiğı) is a Turkish criminal convicted for murdering Council of State member Mustafa Yücel Özbilgin, and wounding four others. He also took part in the bombing of the newspaper Cumhuriyet along with Osman Yıldırım, İsmail Sağır, and Erhan Timuroğlu. All of these events took place from 10–17 May 2006.
Arslan comes from a conservative family. He graduated from Marmara University's law school in 1998. Later on he met fellow Ergenekon suspect Sedat Peker and engaged in financial fraud.
Arslan attended meetings of the Vatansever Kuvvetler Güç Birliği Hareketi (founded 2005) with Muzaffer Tekin.
On 17 May 2006, Arslan killed Council of State member Mustafa Yücel Özbilgin. His stated motive was that the Council disrespected the devout, citing alleged oppression of women who cover their hair; a wedge issue at the time. Allegations surfaced that this was a false flag attack by neonationalists, and Arslan was recruited for the job.
After the attack, the newspaper and his family reported conflicting information over his motives, with progressives blaming conservatives and vice versa. His father, İdris Arslan, also made inconsistent statements to the press.
He was said to have been incited by retired captain Muzaffer Tekin. When his arrest warrant was issued, Tekin attempted suicide. Also detained was major Zekeriya Öztürk. After recuperating, Tekin admitted knowing Arslan, and together attending a 2004 meeting of the neonationalist Association for the Union of Patriotic Forces (Turkish: Vatansever Kuvvetler Güçbirliği Hareketi). Records indicated that the two had made 27 telephone calls between 2004-2006. Tekin said this was related to business they conducted at Doğuş Factoring, which Arslan was the legal counsel to.
It turned out the company's owner, Ayhan Parlak, had written Arslan a check (cheque) for 20,000 Lira before the attack. Parlak was detained for his. Both he and Arslan insisted the check was for legal services rendered. Records showed that Parlak called Tekin 63 times, general Veli Küçük three times, and Arslan 56 times—12 days before the attack.
