Addresses have been raided in Staffordshire by police investigating what they're calling a 'major illegal waste dumping operation'.
Officers teamed up with the Environment Agency to target three addresses simultaneously this morning.
Two of them were business addresses in Stoke-on-Trent and Draycott, and the third was a residential address in Millers View in Cheadle.
Items were seized and taken away to be inspected further by specialist investigators.
Police say they are also in contact with a man that they wish to question regarding the investigation.
Inspector Mark Thorley, commander of the Staffordshire Moorlands local policing team, said: "Today's operation is a great example of how agencies can work together.
"It's been a great team effort and hopefully it will end with a criminal network being disrupted and the dumping of illegal waste prevented in future."
Paul Clarke, lead investigator in the Environment Agency’s National Investigation Team, said: "The Environment Agency takes waste crime seriously and we will persistently pursue those suspected of illegally dumping waste.
"Illegal waste activity of the likes we’re investigating here diverts £1billion from legitimate businesses and the treasury, and at the Environment Agency we do everything we can to bring those responsible to account."
