The discovery of some Ribena bottles that instead of the soft drink actually contained a liquid form of spice has helped police uncover one of the UK's largest prison drug smuggling operations.
Nearly 20 people have been convicted for their roles in the drugs conspiracy, which South Yorkshire Police believe to be worth over £1million.
The investigation began in October 2019 when officers received information that drugs and other unlawful items such as lock knives were being smuggled into HMP Lindholme in Doncaster.
