Student activist Anis Khan had died in February from an accidental fall from a height and wasn’t murdered, the special investigation team (SIT) of police said in its chargesheet submitted to Uluberia court in Howrah on Monday.

The chargesheet also holds five police personnel, including Debabrata Chakrabarty, then officer-in-charge of Amta police station, an assistant sub-inspector of police, a home guard and two civic volunteers responsible for not following the norms of a police raid on Anis’s house in the small hours of February 19.

They have been held responsible for death due to negligence under Section 304 A of the Indian Penal Code (IPC), criminal conspiracy (120B), house trespass (452) along with other sections of the IPC.

The chargesheet states that nine policemen from Amta police station had raided Anis’s house. No general diary entry was made about the raid even though it is mandatory.

“Reports of the state and central forensic labs suggest death from an accidental fall... in this case from the second-floor balcony of his house without a railing,” said a cop.

Anis’s father Salem Khan had alleged that three men attired like civic police volunteers, and a fourth wearing a police uniform and carrying a rifle, had reached his house at 1.10am on February 19 and the trio who looked like civic police volunteers had thrown Anis off the second floor. On Monday, Salem said he stood by what he had said and added that he had no faith in this chargesheet.

The trigger for the police raid was that Anis apparently put up a post on social media on the hijab controversy in Karnataka. Police believed it could trigger social outrage.

The chargesheet states three policemen had positioned themselves on three rooftops adjoining Anis’s Amta house and another behind his house. Four more police personnel were in front of his home and one more at a distance.

Of the four policemen in front of the house, two had entered the house in the wee hours of February 19 and within minutes Anis’s body was found lying in a pool of blood. Almost immediately, the police team had left the spot.

“The chargesheet has been submitted by police who killed my son by pushing him from the second floor of the house. We have no faith in this chargesheet,” Salem said.
