Makarand P Adivirkar was detained for reportedly supplying Bitcoins to a dealer in exchange for LSD. Bitcoins and other kinds of cryptocurrency are frequently used for unlawful transactions on the dark web – websites that aren't indexed and so can't be found using traditional search engines. On November 20 of last year, the NCB seized 20 LSD blots from a drug seller in Kharodi hamlet in the Marve Road region of suburban Malad.
