According to reports, Bollywood actress Deepika Padukone's manager Karishma Prakash has been summoned by the Narcotics Control Bureau (NCB) along with Dhruv Chitgopekar, the CEO of talent management agency KWAN for questioning in a drug case on Tuesday.

A top NCB official related to the probe spoke to a news agency and stated, "We have summoned Prakash, who works as a manager at Kwan and its CEO Dhruv".

The official said that they have been summoned as some WhatsApp chats showed they were allegedly involved in the drug case.

The development comes a day after the NCB officials said they will be issuing summons to Bollywood actors Sara Ali Khan, Shraddha Kapoor, Rakul Preet Singh, and fashion designer Simone Kambhatta this week for questioning in connection with its probe.

Besides Prakash and Dhruv, the NCB has also summoned Sushant`s former manager Shruti Modi and talent manager Jaya Saha for more questioning.

The NCB has already arrested Sushant`s girlfriend Rhea Chakraborty, her brother Showik, Sushant`s house manager Samuel Miranda, personal staff Dipesh Sawant and over 15 others in the case so far.
