Police are investigating after a dead buzzard was found on land near Turnditch with its beak apparently bound.
Wildlife crime officers are working with the RSPB after the bird had a hole forced through its beak which was closed with twine.
PC Emerson Buckingham said: “This bird was most probably alive when it was attacked and may have starved to death as it would have been unable to drink or eat.”
A number of poisoned buzzards were found nearby in Kirk Ireton in 2010. Buzzards are a protected species and anyone caught harming or killing them could face a £5,000 fine or up to six months in prison.
Anyone with information about the incident is asked to call PC Buckingham on 101 or the RSPB on 0845 466 3636.
