As a result of local intelligence police launched an undercover operation, code named Nuffield, targeting groups of drug dealers operating in the Great Yarmouth and Lowestoft areas.

Norwich Crown Court heard that as part of the operation two test purchasing officers were deployed to Yarmouth and Lowestoft and 'achieved a considerable degree of success' in late 2014 and early 2015.

The test officers bought drugs from groups of runners or foot soldiers they had under observation and who were led by Colin Owusu-Asokwa who was said to have played a 'very important and leading role' in the organising of the drugs.

Asowka was said to have 'overall control' of two street dealing groups involved in the conspiracy.
