An FIR has been lodged against Jitendra Narayan Tyagi and others in connection with alleged hate speeches delivered at a Dharma Sansad in Haridwar to incite violence against the minorities, police said.

Tyagi, who changed his name from Waseem Rizvi after converting to Hinduism earlier this month, and other speakers at last week's event have been accused of making extremely provocative speeches and some video clips of it are doing the rounds on social media. Haridwar Kotwali Police station SHO Rakinder Singh said the FIR was registered on Thursday under IPC Section section 153A -- promoting enmity between different groups on grounds of religion, race, place of birth, residence, language -- and the matter is under investigation.
