About 150 brass plaques have been stolen from a remembrance wall at a Kent cemetery.
Tonbridge Cemetery was kept as secure as possible and should be respected by the community, Tonbridge & Malling Borough Council said.
Owen Baldock, from the council, said: "I am absolutely disgusted with the people who do these sorts of things. I find it absolutely incorrigible."
The theft of the plaques was reported on Friday.
Mr Baldock, who is cabinet member for communities, added: "It's so disrespectful to the families of the people whose ashes that are interred there or remembered there."
Each of the plaques were worth about £90 and police have urged scrap dealers to be on the look out for them.
The council said it was contacting the families of those whose plaques had been stolen and it was working with Kent Police to appeal for witnesses.
