Cannabis was seized and a stolen car recovered following early morning raids by South Yorkshire Police in the Thorne area.
Around 100 specialist officers from across the force descended onto land just off Gibbons Lane, just after 7am on Friday 11 January.
Six properties were searched under the Misuse of Drugs Act.
Police say that a number of cannabis cultivations were found and a stolen car recovered. Police estimate the value of the cannabis seized to be over £100k.
Across the day officers made five arrests; two people were arrested on suspicion of cannabis cultivation and three others were arrested on suspicion of theft of a motor vehicle. All have now been released under investigation.
Detective Inspector Steve Smith from Doncaster CID said the operation involved “a huge amount of work from a number of teams”. He added: “I’m pleased with the results we’ve seen.”
