Bhardwaj was detained in Bulandshahr on Friday, hours after the Cockroach Janta Party (CJP) staged a protest outside the Parliament Street police station demanding his arrest over the alleged assault.
Delhi Police added SC/ST Act and criminal intimidation charges to the case after Bhardwaj allegedly claimed he had 'cracked the skull' of a minor activist's father.
Bhardwaj had claimed in an interview that he had cracked the skull of Nishu's father and escaped arrest because of his political connections, triggering widespread outrage on social media.
