The Supreme Court on Monday asked the Haryana government to identify the persons and organisation responsible for holding demonstration in December last against booking of some upper caste people in connection with the Mirchpur dalit killings case. A bench of justices G S Singhvi and A K Ganguly also directed the government and the Railway Board to spell out steps taken by them to recover financial loss caused following the 11-day stir organised by 12 'khap' panchayats. The bench said, there must have been some kind of political backing behind it, while granting two weeks' time to reply. Villagers had been protesting the booking of 98members of their community in the case relating to the killing of 70-year-old Tara Chand and his physically challenged teenaged daughter Suman at Mirchpur village in Hisar on April 21 last year.
