The NCB on Wednesday summoned actors Deepika Padukone, Sara Ali Khan, Shradha Kapoor, Rakulpreet Singh, Simone Khambatta and celebrity manager Shruti Modi in connection with the drugs case.
After Padukone's name emerged in the drug nexus, police security has been deployed outside the residence of the Bollywood actor.
Padukone on Thursday left for Mumbai from Goa Airport as the Narcotics Control Bureau (NCB) has summoned her in connection with a drug case related to the death of actor Sushant Singh Rajput.
A team from the Dadar police station has been deployed outside 'Beaumonde Towers' in Prabhadevi, where the 34-year- old actor owns an apartment, as a precautionary measure, the official said.
Padukone's name has popped up after screenshots of a purported WhatsApp chat between her and her manager, Karishma, surfaced online.
