The mammoth haul – containing 39 kilogrammes of cocaine and 18kg of heroin – had been unloaded and stored at a frozen food warehouse unit in Bilsthorpe, Nottinghamshire.
The consignment – believed to be the biggest drugs seizure in Nottinghamshire for many years – was stowed in a lorry trailer after 26 pallets of frozen yoghurt ice cream had been collected from a factory in Wellens, Belgium.
