Dhirendra Singh, who is accused of shooting dead a man - while in the presence of police and district officials - during an argument at a village in Uttar Pradesh's Ballia, has filed a "surrender application" at a local court. Such an application allows an accused to surrender directly before the court concerned, which will then decide whether to send him to police or judicial custody. So far the cops have arrested two people in connection with the violence, including Dhirendra Singh's brother, and detained five others.
