Uttar Pradesh Police has registered an FIR after receiving a WhatsApp message threatening to kill Chief Minister Yogi Adityanath.

An unidentified person had threatened to blow up the Chief Minister with a bomb.

The sender used objectionable language against Adityanath in the message sent on police headquarter’s WhatsApp number, calling him a threat to a particular community, a senior police officer said.

Senior officers were informed when the message was received around Thursday midnight.

An FIR was lodged at the city’s Gomti Nagar police station and the Special Task Force has been asked to investigate the matter.

Police are investigating if this was an act of mischief or a conspiracy, the official said.

They are looking into the call details of the number from which the message was sent, he said.

An arrest in the case is likely to take place soon, he added.
