An angling club official is waiting for a response from the RSPCA, after reporting the find of four swans' heads in Buckinghamshire.
Steaven Cooper filed his report today, after finding four heads close to Mount Farm Lake, Milton Keynes, during the last three weeks.
A spokesman for the RSPCA said in most instances, the deaths would've been caused by animals, but this could not be established without further investigation.
As he says he has contacted us, I am sure we will get back to him. It is something we would certainly look into. In the majority of such cases, it is down to animal kill, but we do not know in this case until we have looked into it.
