Singh is known as a sharpshooter of Shahabuddin.Police in Siwan have said that Ranjan's killing was part of a pre-planned conspiracy.The Central Bureau of Investigation (CBI) is probing the murder.The apex court also asked the Patna High Court to decide in four months some of the matters relating to the cases against Shahabuddin pending before it.
