Earlier this month, a top police officer and two other cops were transferred in connection with the violence.

Over 80 former bureaucrats had written an open letter alleging failure of the state and central governments in the handling of the December 3 mob violence in Bulandshahr’s Siyana Tehsil.

They had accused Adityanath of bigotry and sought his resignation over the violence in which an on-duty police inspector, Subodh Kumar Singh, and a civilian, Sumit Kumar, died after suffering bullet injuries.

Uttar Pradesh Chief Minister Yogi Adityanath had first called the violence an “incident” but later said that it was a big “political conspiracy”.
