Tipped off by the FBI, Narcotics Control Bureau sleuths arrested the CEO of a Kolkata-based IT firm for his links with an international drug cartel. Sanjay Kedia, an IIT Delhi alumnus, has been remanded to judicial custody for two weeks. The arrest - the first of its kind in India for such a crime - came after FBI stumbled on a syndicate in the US that was operating an online pharmacy selling banned psychotropic substances.
