Police are appealing for information after copper pipes were stolen from a training centre in Morpeth.
Thieves broke into Fulbeck Grange Training Centre and sawed through a door to get into a boiler room, where they then removed the copper piping.
The theft is thought to have happened at some point between Thursday 6 December and Wednesday 6 March.
– Morpeth Inspector Dave Simpson
"The thieves sawed through a wooden door to get access to the pipes so we are asking people to ask themselves whether they saw or heard anything suspicious in the area.
"We would also like to hear from anyone who has been offered copper pipe for sale."
Anyone with information is being asked to contact police on 101 or to ring the independent charity Crimestoppers on 0800 555 111.
