Seven people including a 17-year-old boy have been arrested after goods such as six caravans were suspected to have been stolen.
Kent Police’s Rural Task Force, alongside officers from the Thames Valley Police, carried out a search of a property in Swattenden, Cranbrook at around 7.30am last Friday (April 26).
Officers were originally searching for a power tool with a tracking device after its owner is said to have been repeatedly targeted by thieves.
However, more than 1,000 suspected stolen items were eventually seized.
Recovered items included four vehicles and a quad bike which is believed to have been taken from Ashford.
A large quantity of power tools, plus six caravans suspected to be stolen from Bristol, Wales, Southampton, Staffordshire, and Sussex were also found.
It is believed their combined value will exceed £500,000 once police complete their investigation.
Investigators have since arrested seven people from Cranbrook in connection with the incidents.
Five men aged between 18 and 44 were arrested alongside a 19-year-old woman and 17-year-old boy on suspicion of multiple offences relating to theft.
They have since been bailed pending further investigations.
Police say it is one of the largest hauls of suspected stolen items they have encountered.
Sgt Ross Haybourne, of Kent Police's Rural Task Force, said: "We hope to reunite as many of the items as we can with their rightful owners as soon possible.
"Officers are in the process of cataloguing the suspected stolen items and a comprehensive list will be released to the public in due course.
"Anyone wishing to claim items listed will need to provide proof of ownership or proof of purchase.
"We anticipate this to take a considerable amount of time and thank the public in advance for their patience while we undertake the task.
"Any tradespeople, or those in possession of power tools, are advised to mark their property, take photographs, and record serial numbers so that, in the event of theft, officers have more chance of returning property.
"We also advise reporting any thefts in a timely manner, providing as much detail as possible."
