Police have booked Fahim Khan, key accused in the Nagpur violence, and five others on charges of sedition and spreading misinformation on social media, officials said on Thursday, adding that curfew was lifted or relaxed in parts of the city three days after the violence. Maulana Shahabuddin Razvi, a Barelvi sect cleric, wrote to Union home minister Amit Shah, seeking a ban on the film 'Chhava', alleging it was inciting communal tensions and was directly responsible for the Nagpur violence.
