Peker was born in Sakarya, Turkey. He spent considerable time in Germany. He is a noted Turanist.
Peker was tried for the murder of the drug smuggler Abdullah Topçu, but acquitted. The two other defendants in the same case, considered to be Peker's employees, were sentenced to lifelong imprisonment.
After this, he fled to Romania and was sought for, amongst others, protection racketeering, coercion, and incitement to murder. During this time it was reported that he had been visited by a minister and a member of parliament from the Motherland Party and guaranteed, in return for an unknown favor, to be only imprisoned for a short period of time.
On 17 August 1998 Peker was brought to Turkey of his own free will and surrendered to the authorities. The case against him was opened in September 1998. He pleaded guilty to the crimes for which he was accused and was found guilty of building a criminal organization. During the trial, Peker made some interesting remarks, which he never cleared up: " An older member of parliament sent me an SMS which said I shouldn't behave too arrogantly. I would like to tell you (the court) everything, because if I don't it could come to pass that I commit suicide under suspicious circumstances." The Prosecutors requested at least 7.5 years imprisonment, but Peker was only sentenced to eight months and 29 days and was released on 14 May 1999.
On 12 May 2005 he was arrested during Operation Butterfly. On 31 January 2007 he was found guilty of building and leading a criminal organization, robbery, forgery, and two counts of false imprisonment, and sentenced to 14 years 5 months.
