Aryan Khan's WhatsApp chats appeared to reveal that he regularly indulged in "illicit drug activities", a special court in Mumbai said on Wednesday, as it turned down the bail application filed by the son of Bollywood superstar Shah Rukh Khan in the drugs-on-cruise case. "WhatsApp chats prima facie reveals accused Aryan Khan is dealing in illicit drug activities for narcotic substances on regular basis. Therefore, it cannot be said that Khan is not likely to commit similar offence while on bail," Judge VV Patil said in his order.
