SP MLA Irfan Solanki said that he noticed a picture on Facebook which looked like a news footage of a national news channel and showed him raising pro-Pakistan slogans.
The channel's logo and the news anchor were also visible in the picture, he said, adding that when he approached the channel's local reporter he denied of running any such news.
The head office of the channel also denied of running any such story. When the photo was inspected thoroughly, it was found to be morphed, the MLA said.
He also alleged that Gupta is a BJP worker and posted the picture to tarnish his image.
The reporter complained against Gupta and the morphed picture to the Crime Branch in Kotwali police station, Senior Superintendent of Police Shalabh Mathur said.
On the basis of the reporter's complaint, an FIR has been registered and an investigation is underway, the SSP added.
