Chhattisgarh Police have registered an FIR against Hindu religious leader Kalicharan Maharaj on the charge of promoting enmity between classes after he used derogatory words against Mahatma Gandhi and hailed his assassin Nathuram Godse, an official said on Monday.

During the conclusion of the two-day 'dharma sansad' at Ravan Bhata ground in Raipur on Sunday evening, Kalicharan had used an "abusive" word against the Father of the Nation and asked people to elect a staunch Hindu leader as the head of the government in order to protect the religion.
