The Narcotics Control Bureau (NCB) has detained one of Mumbai's "biggest" drugs suppliers, and recovered a list of his clients many of whom are Bollywood celebrities, agency sources said, adding that this could be "one of the last links" in the drugs case related to actor Sushant Singh Rajput's death. Accused, Azam Sheikh Jumman, allegedly got drugs directly from Himachal Pradesh and gave them to even bigger suppliers.
