The singer was booked under section 294 of IPC (Obscene acts and songs), police said.
On Tuesday after it was pulled up by the High Court for "inaction" on the matter, the Home Department had given the go-ahead to Nawanshahar police to register a case against the singer for his song 'Main Hoon Balatkari' (I am a rapist.)
About two weeks ago, the department of cultural affairs had submitted a report to the state home department, recommending action against the singer, who has been courting controversies for his songs based on sexual themes.
