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.
When officers searched prison nurse Amy Hatfield's belongings, they found multiple wraps of cannabis, tobacco, anabolic steroids, vials of liquid, MDMA, phones and chargers.
The 37-year-old also had several bottles of Ribena, which in fact contained a liquid form of the synthetic cannabinoid spice, Detective Sergeant Gareth Gent, head of South Yorkshire Police's Prison Anti-Corruption Unit, said.
He added: "The prison value of the liquid spice recovered from Hatfield that morning was estimated by prison experts to be around £1 million.
"That quantity of drugs found on one person going into the prison was undoubtedly shocking and set alarm bells ringing that this was part of something much bigger.
"As we started to dig into Hatfield’s associates and connections, little did we know that we would uncover such large-scale criminality."
Following a large-scale police investigation, officers discovered co-conspirators, arresting and charging them with multiple offences linked to the smuggling of substances and phones into prisons for large sums of cash.

Talking about Thursday's last trial, DS Gent said: "Yesterday marked the culmination of a four-year investigation into one of the most significant and complex prison conspiracies in the country, unravelling a network of criminals both in and out of the prison system working to smuggle dangerous and illegal substances into custody for money.
"Our investigation began back in October 2019, after we received information that drugs and other unlawful items including lock knives were being smuggled into HMP Lindholme.
"We attended at the prison and arrested a mental health nurse as she arrived for her shift and what we found led to the unravelling of this group's criminal enterprise."
He added: "As a result of our tireless determination to uncover this criminal network, we have disrupted and dismantled an incredibly dangerous drugs operation that posed a significant risk to the prison population, it’s staff and the wider community."
