The Deputy Commissioner, Revenue (East), issued a notice to police to submit within two days details about deployment, police firing and log details of wireless sets, a government official said.

Police said 35 policemen and four from the public were wounded in the violence. While one was killed from “suspected” bullet wounds, police said they did not fire at the mob.

Divisional Commissioner Vijay Dev said the National Human Rights Commission rules mandate a magisterial probe in such cases to ascertain the police’s responsibility.

Dev said crucial evidence has been seized in the case to fix responsibility. “Allegations of police firing, using baton, the attempt to sabotage the fire brigades rather than douse the fire has to be explained. The inquiry will look into the events that led to the incident,” Dev said.

Delhi Police PRO and Additional DCP (Crime), Rajan Bhagat, said 13 people have been arrested for for the violence in Khoda village that went on till early Monday. They are charged with rioting, arson and attempt to murder.

“Police teams fired 120 teargas shells. A case each has been registered at Ashok Nagar and Ghazipur police stations. Altogether 35 police personnel were injured, including the SHO of Ghazipur police station, whose hand and leg were fractured. ACP Kalyanpuri, a constable and a head constable were among those who were severely injured,” Bhagat said.

He said Vinod Singh Negi, who was part of the mob, died from a “suspected” bullet wound. “Police did not open fire,” Bhagat said.

The four others injured are brothers Saurav and Rahul, Praveen who sustained a wound in his abdomen and Anil Verma, who was hit by a bullet in his shoulder.

Police said rumour that a man on a scooter died at a checkpost after he was flagged down for not wearing a helmet triggered the violence and arson. Police said the man was drunk and he rammed into a barricade.
