MUMBAI: Bollywood actor Ananya Panday failed to appear before the Narcotics Control Bureau on Monday for the third round of questioning in connection with her alleged WhatsApp chats with Aryan Khan, arrested in the cruise drug seizure case. Sources said she sent a message to the NCB saying she is unwell and sought time to appear before them. NCB zonal director Sameer Wankhede too was unavailable as he had to visit the agency’s headquarters in Delhi. Last week, the NCB had questioned Panday twice and carried out a search at her residence. Officials said that there are WhatsApp chats between Khan and Panday discussing procurement and consumption of drugs.
