BETWEEN 300 and 400 gallons of diesel used for farm vehicles was siphoned from Droitwich between 6pm on Sunday (October 18) and 9am on Monday (October 19).
The incident happened in Shernal Green when raiders approached an outbuilding used as a workshop and storage for tractors.
They forced off two padlocks which secured the wooden doors and took the fuel by removing a locking cap from a metal diesel tank.
A large amount of hand tools, including spanners and screwdrivers, were also stolen.
To get to the building, the thieves crossed a field and climbed over a sty – where some of the stolen hand tools were left as the burglars escaped.
Witnesses or anyone with any information should call police on 101 or Crimestoppers on 0800 555 111.
