A goose has been shot with a crossbow at Poolsbrook Country Park near Staveley.
The incident is believed to have taken place on Saturday morning, although exact details are still uncertain.
A number of residents saw the stricken animal, one person taking a photo clearly showing the arrow sticking through its upper body.
One shocked visitor, Lee Turner, wrote on Facebook: “My faith in humanity has been crushed.
“I have just witnessed a swan limping out of Poolsbrook pond with a crossbow bolt through its chest.
“I couldn’t help the poor thing☹, it wouldn’t let me near. I could only call the RSPCA.
“You callous, twisted, sick minded b******s. How could you do such a thing to a defenceless creature?”
