The investigation into the Aryan Khan drugs case has been transferred from the NCB's Mumbai zone to a central team. Sameer Wankhede will no longer supervise the probe. Now, this has intensified politics. Notably, five other cases, including the one pertaining to Maharashtra minister Nawab Malik's son-in-law Sameer Khan, have been transferred from the NCB's Mumbai zone to the central zone. Sanjay Singh, the deputy director-general of the central unit of the NCB, will now be the supervising officer for all five cases. Meanwhile, a vigilance probe against Sameer Wankhede is currently underway. The probe was initiated by the NCB after allegations of extortion were leveled against Sameer Wankhede in the course of the investigation into the Mumbai cruise drugs case. Watch this video.
