Four men wearing gloves and face coverings stole £25,000 worth of tools from a commercial premises in Midhurst last week, according to Sussex Police.
Police are appealing for witnesses following the break-in at the site of Works Yard on the Cowdray Estate, in Easebourne Lane, on Thursday, April 25.
A police spokesman said: "A Land Rover Defender was driven onto the site between 9.30pm and 10pm.
"Four men, all wearing gloves and face coverings, were then seen to break into four vans and a garage, stealing a large number of tools, three strimmers and a water pump.
"The total loss in thefts and damages is estimated to be in the region of £25,000."
