Maharashtra minister Nawab Malik's relentless attack on the anti-drugs agency amid the probe in Aryan Khan case continued this morning as he said that Sameer Wankhede, the officer spearheading the investigation, "did not follow proper rules" in 26 cases. Citing a letter from an unnamed NCB (Narcotics Control Bureau) employee, Mr Malik said Mr Wankhede was "brought to the NCB by Home Minister Amit Shah and ex-CBI officer Rakesh Asthana".
