12 Sheep Killed In Bucks Dog Attacks
12 sheep have died in two separate dog attacks in South Bucks.
Police say they happened on Saturday and Monday near Bellingdon and five other sheep were injured.
Sgt James Ellis, of the Chesham Neighbourhood Policing Team, is appealing for witnesses and also has advice about keeping livestock safe.
He said: "Clearly this is a serious incident and as well as the distress caused to the livestock there is also the financial impact on the farmer concerned."
"We recognise that this issue is also of concern, to the wider farming community and we are keen to help them come together and provide us with any information they may have that can help us with our investigation into these incidents.
"We would ask that all those in the Bellingdon area remain vigilant, particularly keeping an eye out for dogs escaping their boundaries, and report anything of concern they see.
"It may be that a resident in the Bellingdon area has had their dog return home looking like it may have been involved in an incident of this nature and, again, we would urge them to report this to us.
"Responsible dog owners know where their dogs are – please be aware of where your dog is at all times. It is a criminal offence to not have your dog under control.
"If anyone has any information which could help to trace the dog, please call Thames Valley Police via the 24-hour enquiry line 101.
If you don't want to speak directly to the police then you can contact the independent charity Crimestoppers anonymously on 0800 555 111. No personal details are taken, information is not traced or recorded and you will not go to court.
