The Central Bureau of Investigation on Thursday registered a case of murder against 11 people and started collecting forensic evidence in Sunped village, where two Dalit children were killed after their family was set on fire on October 20. The case was handed over to them by the local police, who had registered an FIR against the accused, the Press Trust of India reported.

The team is headed by a Deputy Inspector General-level officer and is trying to unearth the circumstances under which the attack took place. It is suspected that upper-caste villagers were behind the crime, as there has been tension between them and the Dalits in the past. The children’s parents also sustained severe injuries in the arson attack, and their mother is still in critical condition at the Safdarjung Hospital in Delhi. The Haryana government had ordered a CBI probe into the incident after it sparked widespread outrage in the country.
