In a sensational claim, film producer Kshitij Prasad's lawyer has told the Bombay High Court that Prasad was asked by the Narcotics Bureau to implicate filmmaker Karan Johar in the drugs case. Prasad, who is in NCB custody in a widening drugs probe linked to Sushant Singh Rajput death, has alleged that he was harassed and blackmailed by the agency. He has claimed that the NCB offered to let him off if he can implicate Karan Johar and other Dharma Productions executives. Last week, Karan Johar had denied claims that Kshitij Prasad was associated with his firm. The NCB has reportedly denied Prasad's claims.
