Is it a criminal offence to click a photograph of a on duty uniformed police personnel?

Hello Amlan Sarkar, I acknowledge your question. In many states it is clear and completely legal to do so to the extent that such an does not lead to nuisance. Calcutta HC ruled in 2008 that a police officer cannot snatch a mobile phone merely because his video was recorded as he is a public official in execution of his duty. The same is also mentioned under the Kerala Police Act 2011 under Section 33(2) that reads as “No Police Officer shall prevent any member of the public from lawfully making any audio or video or electronic record of any Police action or activity carried out in a public or private place.” It would be held the same with your respective state too. The intentions are to be considered majorly, since the police personal can also file a complaint against you under section 354 of IPC, section 66E of IPC dealing with punishment for violation of privacy, and explicitly forbid capturing, publishing or transmitting ‘the image of a private area of any person without his or her consent. It is a criminal offence to do so.

I hope I have answered your question.

Have a good day.
