An investigation had been launched after a teenager found a number of cow heads lined up along a rural road.
Mary Hiscock’s 17-year-old daughter made the gruesome discovery on her way to work in Kent on Thursday and saw a further four heads added to the collection of dead animals days later.
Six heads and entrails were seen sitting side-by-side in Tilsden Lane with one of the calves’ mouths having been cable-tied shut.
Mrs Hiscock’s two daughters have since reported the mutilated cow corpses to Tunbridge Wells Borough Council.
She told Kent Online: “My daughter first saw two heads on Thursday night and then she saw some more on Sunday when she was going to work.
“The heads were all lined up and their entrails were there. They were in disbelief.
“My 17-year-old daughter was quite taken aback by it and now she thinks it might be some kind of cult ritual.”
Reports on social media suggested the heads may have been left for hunters to pick them up and dispose of them while the smell was also described as “foul”.
Mrs Hiscock added: “It’s a bizarre scene and looks almost sacrificial, but almost certainly like it has been arranged like that. They definitely didn’t die there.
“If it was a dump job then it would have been littered in all directions but they seemed to be specifically lined up. It is quite bizarre.”
Kent Police, RSPCA and Tunbridge Wells Borough Council have said they are yet to receive any reports of dead animals being dumped in the area.
Cranbrook Parish Council have also reported the matter to the relevant authorities while a spokesman described it as “bizarre, unpleasant and worrying”.
This comes just days after police warned farmers or smallholdings with livestock to be vigilant after sheep were found slaughtered in separate attacks.
In a similar incident, a manhunt was launched by police in the West Midlands after a ewe and a calf were killed by raiders on a farm.
