The Chhattisgarh police have registered an offence against a man for allegedly posting a doctored video on social media of pro-Pakistani slogans being raised during the Congress' 'Bharat Jodo Yatra', an official said on Saturday.

A member of the Congress legal cell lodged a complaint in Raipur on Friday, following which an FIR was registered against a man, who hails from neighbouring Madhya Pradesh, said Satyaprakash Tiwari, the station house officer of Civil Lines police station said.

In his complaint, a member of the Congress legal cell Ankit Kumar Mishra alleged that the accused had on Friday posted a doctored video of the yatra on his Twitter handle, in which pro-Pakistan slogans were raised, he said.

An offence has been registered under section 504 (intentional insult with intent to provoke breach of peace) and other relevant provisions of the Indian Penal Code (IPC) and a probe has been launched, the official said.

BJP IT cell head Amit Malviya posted the video of the Yatra in which former Congress president Rahul Gandhi, party general secretary Priyanka Gandhi Vadra and Madhya Pradesh Congress president Kamal Nath are seen walking and a voice purportedly shouting "Pakistan Zindabad" is heard towards the end of the 21 second clip.

"After Richa Chaddha's public application to join Rahul Gandhi's Bharat 'Jodo' Yatra, 'Pakistan Zindabad' (listen towards the end of the video) slogans raised in Khargon. INC MP posted the video and then deleted it after the faux pas came to light. This is Congress's truth ," Malviya tweeted.

Hitting back, Congress' general secretary in-charge communications Jairam Ramesh said a video "doctored" by the "dirty tricks department" of the BJP is doing the rounds to discredit the "highly successful" Bharat Jodo Yatra.

"We are taking the necessary legal action immediately. We are prepared for such tactics, and there will be payback," he said on Twitter.

In another tweet, Ramesh also alleged that the Madhya Pradesh government "intimidated" and aggressively prevented tribal families displaced by the diamond mining project in Chhatarpur district from meeting Rahul Gandhi this afternoon.

"This is democracy-BJP style," the Congress leader said.
