Anish Dundoo, a 29 year old US Citizen, was arrested in Hyderabad, India after the examination of phone records by drug peddlers who were previously arrested led authorities to 1.2 kilos of marijuana and 16 LSD blotters in an office to Dundoo's business. Dundoo's arrest led to his business partner's arrest, Ritul Agrawal, a 26 year old steel businessman. Both Agrawal and Dundoo would use bitcoin and other cryptocurrencies to purchase narcotics online, received through Netherlands marked courier packages. Dundoo's records indicate that he visited dark net marketplace "Lunacy" at least 8 times and phone records indicate that his narcotics were being purchased by hundreds of college and high school students all the way as young as 8th grade. These busts in India come with an increased effort in detective work.
