A case was registered against 50 unidentified people in Indore in Madhya Pradesh for protesting against the arrest of Hindu religious leader Kalicharan Maharaj, who was held last week for using an expletive for Mahatma Gandhi during a speech at an event on December 26 in neighbouring Chhattisgarh, an official said on Monday.

A video of the protest, which was held on Sunday, also showed some people shouting slogans in praise of Nathuram Godse, the Mahatma's assassin.
