Three more accused were arrested on Saturday in connection with the murder of Deputy Superintendent of Police (DSP) Surendra Singh in Gurugram, Haryana. So far, a total of six people have been arrested in this case. A new twist came in the case when the lawyer of accused Ikkar said that he is mentally unable. Meanwhile, Ikkar's lawyer submitted a disability certificate to the Nuh police, claiming that the accused was mentally challenged and had nothing to do with the case. Ikkar's lawyer Imran Khan said, “Whoever sees Ikkar from the front will immediately understand that he is insane. We have handed over his disability certificate to the Nuh police. We are waiting for the response of the police, if we do not get a reply, we will approach the Human Rights Commission.” Ikkar was arrested on the same day of the incident. Ikkar was a co-driver in the same truck that had crushed the DSP. According to officials, Bhuru alias Taufeeq and Asru alias Asruddin, residents of Pachgaon in Haryana and Lambu alias Yusuf, residents of Gandwa village in Alwar district in Rajasthan were arrested on Saturday.
