After questioning Bollywood actor Rakul Preet Singh on Friday for over four hours, Narcotics Control Bureau (NCB) is all set to interrogate Bollywood divas Deepika Padukone, Sara Ali Khan and Shraddha Kapoor today. The actresses have been asked to join the drugs probe at 10 am today. While Deepika will be cross-examined with her manager Karishma Prakash, Sara and Shraddha will be asked about late actor Sushant Singh Rajput and the parties they attended together. Karishma was interrogated by the NCB on Friday as well and was asked about the WhatsApp chat in which the Bajirao Mastani actress can be seen asking for ‘hash’ from her. Karishma confessed that Deepika was the admin of the WhatsApp group with her, Jaya Saha and Deepika as the members.
