Actress Rakul Preet Singh, who has been summoned by the Narcotics Control Bureau (NCB) in the Bollywood drugs probe case, will be questioned on Friday.
Deepika Padukone, Sara Ali Khan and Shraddha Kapoor have been called in on Saturday. Deepika and Sara, who were in Goa, returned to Mumbai on Thursday.
Deepika Padukone's manager, Karishma Prakash, will also be grilled on Friday, according to reports.
Karishma's WhatsApp chats included conversations about drugs with one `D' and central agency wanted to find out who this person was, NCB sources had said earlier.
Meanwhile, statements of fashion designer Simone Khambatta and Shruti Modi, Rajput's former manager, were recorded by the NCB probe team in connection with the drugs case, the official said.
The NCB, which began the inquiry after a drugs angle came to light in connection with Rajput's alleged suicide, has now widened its investigation and asked a clutch of Bollywood celebrities to "join the probe".
