A Delhi court today dismissed the Nirbhaya gang rape and murder case convict Vinay Kumar Sharma's plea. Sharma had claimed that he had a mental illness and needs treatment.<br />'' <br />'' Additional Session Judge Dharmender Rana rejected Sharma's plea that had claimed he had sustained a grievous head injury and fracture in his right arm and was suffering from "insanity", "mental illness" and "schizophrenia".<br />'' <br />'' Tihar jail authorities had termed his claims as a "bundle of distorted facts" and told the court that CCTV footage established that the convict had inflicted "superficial" injuries on himself and was not suffering from any psychological disorder. The psychologist, who appeared on behalf of the jail, said medical checkups of all four convicts were done on a daily basis and they are all fine.<br />'' <br />'' The court had on February 17 issued fresh death warrants for execution on March 3 at 6 am against the four death row convicts in the case. It had issued fresh warrants against death row convicts — Mukesh Kumar Singh (32), Pawan Gupta (25), Vinay (26) and Akshay Kumar (31).
