Kerala state BJP president Kummanam Rajasekharan has been booked for posting a video where he alleged that CPM workers were seen celebrating the murder of an RSS worker.
Kannur Town police registered the case against him under IPC Section 153.
State police chief TP Senkumar had earlier in the day asked Kannur SP G Siva Vikaram to begin a probe into the complaint against the state BJP chief over his social media post.
The complaint alleged that the BJP leaderâ€™s tweet was intended to cause friction among political parties.
Following RSS worker Bijuâ€™s murder at Payyanur in Kannur, Kummanam had tweeted on May 13: Brutality, beastiality at its worst- Kannur Communists celebrate murder of RSS Karyakartha Biju, whom they beheaded. #JungleRajInKerala'.
Kummanam had further tweeted, â€śCelebrating death is a CPI(M) hobby. Hanging dogs at the spot of Manoj's murder, victory march after KT Jayakrishnan's (RSS school teacher who was killed in front of students) judgement are instances.â€ť
He also posted a video, which allegedly showed CPM workers dancing and celebrating his murder.
A CPM worker from Thillankery in Kannur, Muhammed Siraj, had earlier petitioned CM Pinarayi Vijayan and state police chief TP Senkumar to book Kummanam under Section 153A of the IPC.
The petition stated that he posted the video with criminal intent to provoke BJP and RSS activists into unleashing attacks against CPM activists.
On Monday, Kerala Chief Minister Pinarayi Vijayan told the state assembly that Kummanam would face criminal proceedings if it was proved that the video he posted was false.
â€śThere is no authenticity for the video. If it turned out to be fake, the police will have to file a case against Kummanam. It is not clear where it was taken,â€ť CM said.
