ABOUT 300 litres of oil has been stolen from a storage tank in St John's.
It happened at a private residence in the Tynwald Mills area between October 13 and 23.
A police spokesman said: "The volume of oil stolen would have taken considerable time and would have undoubtedly required more than one person to commit the theft."
Anyone with information should contact Police Headquarters on 631212 or Crimestoppers on 0800 555 111.
