Laddan Miyan, a key accused in the murder of Bihar's senior journalist Rajdeo Ranjan, surrendered before a Chief Judicial Magistrate Court in Siwan, on 2 June. Miyan is also a close aide of former RJD MP Shahabuddin.
The development comes after the arrest of five people in connection with the scribe's brutal murder.
The Bihar Police had earlier said that initial investigations into the murder of Hindustan daily's Siwan bureau chief Ranjan indicated at the possible involvement of jailed RJD leader Mohammed Shahabuddin.
According to an NDTV report, interrogations revealed that it was Miyan who had commissioned the contract for Ranjan's murder. He had reportedly paid Rs 15,000, and promised to help out one of the five accused in settling a land dispute.
Miyan, who had been released from jail 15 days before Ranjan's murder, left Siwan with his family two hours after the crime, the police revealed.
Ranjan, a journalist with over 20 years of experience, was shot dead in Bihar's Siwan district on 13 May.
Five shots were fired at him from extremely close range near Siwan's railway station.
Ranjan was rushed to the hospital where he was declared brought dead.
