The columnist, Shefali Vaidya, lodged a complaint based on which a case was registered against Mr Mevani on June 3 at Paud police station under IPC Section 500 (defamation) and Section 66 (C) of the Information Technology Act, said a police official.
According to the police, Mr Mevani tweeted a picture of Uttar Pradesh Chief Minister Yogi Adityanath, spiritual leader Sri Sri Ravi Shankar and Ms Vaidya together on May 29 along with a still from Hindi film 'OMG - Oh My God!' and allegedly drew a parallel between the two images in his tweet.
Mr Mevani later acknowledged that he had tweeted a photoshopped picture and deleted the contentious tweet.
"I am told that this is a photoshopped image. Apologies for posting it without verification. Deleting my previous tweet now and will be careful in future.
Ms Vaidya, however, approached the police and registered a complaint alleging Mr Mevani had downloaded her photo from her social media account, cropped and morphed it and used it in his tweet.
Mr Mevani, by allegedly posting defamatory comments against her and circulating the morphed image on a micro-blogging site, caused mental harassment to her and her family, the complainant said.
