The Narcotics Control Bureau (NCB) on Saturday questioned Bollywood actresses Deepika Padukone, Sara Ali Khan and Shraddha Kapoor in connection with the probe into an alleged drug nexus involving members of the film industry. The probe was initially triggered by the investigation into the death of actor Sushant Singh Rajput and led to the arrest of his live-in partner Rhea Chakraborty for the procurement of drugs on his behalf. Now NCB has got evidence against big celebrities of B-town and agency is going to take action very soon.
