Four swans have been found beheaded at a popular beauty spot in Milton Keynes.
The number of swans at Mount Farm Lake near Bletchley has more than halved recently, prompting fears that many others have been attacked.
A member of the local angling club, Steven Cooper found the remains and couldn't believe what he saw.
The RSPB says deliberately harming a swan is a wildlife crime. They have described the incidents in Milton Keynes as "sickening attacks".
