London: A "prolific" smuggling ring led by the CEO of an India-based pharmaceutical company has been busted by the UK security forces, following an investigation across 26 countries over six years, officials said here on Thursday. The UK's National Crime Agency (NCA) said its investigation had identified around 42 tonnes of importations of illicit anabolic steroids into the UK and all major players in the smuggling operation have now been brought before the court. The NCA directly linked Jacob Sporon-Fiedler, the 38-year-old CEO of India-based Alpha Pharma, to around 16 tonnes of the imports with an estimated value of around 12 million pounds. Sporon-Fiedler worked with a network of UK-based fixers, including 65-year-old Gurjaipal Dhillon and 44-year-old Nathan Selcon. Together they were responsible for arranging dozens of unlicensed shipments of drugs from India into Europe, and then distributing them. The illegally imported drugs - made by Alpha Pharma in India - were shipped using Dhillon's contacts. Once in the UK they would be distributed by Selcon to be sold to bodybuilders and fitness fanatics on the black market. "This organised crime group was the most prolific of its kind ever uncovered, likely the biggest global players in the illicit anabolic steroid market," said NCA branch commander David Cunningham.
