The wooden roof may be damaged by exposure to the elements
Thieves have stolen part of the copper roofing from a war memorial in the Black Country.
Metal strips were ripped off the Barr Beacon war memorial in Walsall either on Friday night or Saturday morning.
Adrian Andrew, deputy leader of Walsall Council, said:"It's shocking and disgraceful."
He has asked scrap metal merchants not to buy any copper that has gone green on one side as he said it could have come from Barr Beacon.
"I don't know what kind of society that we live in where a war memorial can be attacked in this fashion just for some financial gain by some very undesirable people in society," Mr Andrew said.
Beneath the copper, the memorial has a 100-year-old wooden roof that could be damaged by exposure to the elements, he added.
Anyone with information about the copper is asked to contact West Midlands Police or call Crimestoppers.
