Police have booked a suo motu case against Telangana BJP MLA T Raja Singh, right wing outfit Sri Rama Sene chief Pramod Muthalik and two others for alleged "inflammatory" speeches in north Karnataka three days ago.

Police said the four leaders, besides a large number of people, raised slogans and gave speeches that amounted to creating hatred between communities at the 'Hindu Dharma Samavesha', organised by the Sene at Yadgir on December 12.

BJP leader Vijay Patil and Siddalinga Swamy of Karuneshwara Mutt were the other two against whom the cases had been booked, they said.
