The police are looking for the accused Nagesh Lad and have recorded a case under the Indian Penal Code (IPC) sections 302 (murder) and 307 (assassination attempt). Lad had been on bail for about a month, according to police, after being sent to prison for breaking IPC section 326 (causing grievous hurt). "Because of his criminal background, Lad's parents disowned him and he stayed in different places.
