Police discovered the van packed full of cannabis plants as it was being moved from a flooded property in Worksop. The drugs are thought to have a total street value of over £20,000.
The driver, a 26-year-old man, was detained nearby and arrested on suspicion of production of cannabis and being concerned in the supply of cannabis. He has since been questioned and released under investigation pending further enquiries.
Following the arrest, officers carried out a search warrant at a property in Market Street, Worksop - which had been affected by the recent floods in the town.
Inside they found the cellar had flooded, making the bypassed electricity supply to a cannabis grow upstairs dangerous. Officers seized one remaining cannabis plant and growing equipment from the attic.
"What started as a relatively routine vehicle stop led to the discovery of a large quantity of drugs. "The flooding has had a big impact on the town of Worksop, causing misery for a number of families who have had to leave their homes. However, it appears it has also had the impact of flushing out some criminal activity by halting some large-scale cannabis production."
Enquiries are continuing into the incident and anyone with information is urged to contact Nottinghamshire Police on 101, or Crimestoppers anonymously on 0800 555 111, quoting incident number 946 of 10 November 2019.
