A NEWLY-LAID memorial at Dewsbury Cemetery was damaged by council workmen cutting grass.
Jason Ginnelly, of St John Parade, Westtown, was shocked to find chips in the stone commemorating his parents.
The tribute was laid on September 18 and by the time he visited again on September 27 it had suffered damage valued at £452.
He has since been locked in a battle with Kirklees Council - who have now admitted responsibility and will pay for repairs.
It is believed other graves in an area near Dewsbury Cemetery’s entrance on Ravenshouse Road were also damaged.
Kirklees are now working with their insurers to cover damage which could cost taxpayers thousands of pounds.
Jason, 38, said: “It was really upsetting. Within a week of it being laid the memorial was chipped by a lawnmower.
“I asked the cemetery manager how this could’ve happened and was told some council workmen did it.”
He found the damage on a visit to the memorial on what would have been his dad William’s 76th birthday.
Mr Ginnelly died in March and the ashes of Jason’s mum Jacqueline were interred with him at the memorial site.
Jason added: “Perhaps this wouldn’t happen if workmen didn’t ride around like crazy and watched where they were going.”
A council spokesman said: “This type of incident is not a regular occurrence but it does happen occasionally.
“The council has been in touch with the families affected and apologised for any distress caused by the incident.”
