Two buzzards found in woodland last year are thought to have been poisoned TWO men are being questioned following raids by a team investigating the illegal killing of birds of prey. Durham police officers teamed up with partner agencies on a special operation to target raptor persecution, which included searches at two properties in Teesdale this morning. Operation Sunbeam included members of the Barnard Castle Neighbourhood Policing Team, RSPB, Natural England and the National Wildlife Crime Unit. It follows an incident last year when two common buzzards were found dead in Teesdale woodland. Forensic tests indicate they were illegally poisoned with a banned pesticide.
