Actor Rakul Preet Singh today appeared before the Narcotics Control Bureau (NCB) to record her statement in connection with the agency's drug probe linked to filmstar Sushant Singh Rajput's death. Actor Deepika Padukone's manager Karishma Prakash has also reached the NCB guest house, from where the central agency is operating, in Colaba to join the probe, officials said. This is the first time that both Rakul Preet and Ms Prakash appeared for questioning before the anti-drug agency that has launched an inquiry following chats retrieved from the phone of arrested actor Rhea Chakraborty.
