They were arrested in November 2014 in a sting operation by US Drug Enforcement Agency (DEA) officers posing as Colombian drug dealers. Goswami and his aides were accused of conspiring to ship at least 98 kg of high-grade heroin and methamphetamine to the US.On April 14, the Thane crime branch seized over 20 tonnes of ephedrine and 2.5 tonnes of acetic anhydride, both banned party drugs from a pharmaceutical factory in Solapur and other locations in Thane and Mumbai.
