Actors Deepika Padukone, Shraddha Kapoor, Sara Ali Khan and Rakul Preet Singh have been summoned by the Narcotics Control Bureau (NCB). Deepika Padukone has been summoned by the NCB on the basis of WhatsApp chats. The chats were procured from actor Rhea Chakraborty's phone that led the anti-drug agency to Deepika Padukone's manager Karishma Prakash. Is this a big clean up operation or just a witch hunt?
