Laddan Mian, who was prime accused in the killing of Bihar journalist Rajdev Ranjan, surrendered before a local court.

Mian was released from the Siwan jail just two weeks prior to the murder. He hired youngsters with no criminal background to carry out the killing.
Police had earlier arrested five persons in regard to the murder of Ranjan. They have confessed that hat they had killed Ranjan at the behest of Laddan Mian who had promised them to settle a land dispute and Rs. 15,000.
Bihar government had recommended a CBI probe into the murder but, the agency is yet to take up the case.
Ranjan, a senior journalist, was shot dead in Bihar on May 13 evening. Two shots were fired at him at extremely close range near Siwan’s railway station.
