Sadly the incident would appear to be genuine. On Friday night / Saturday morning, very close to where I live, three persons from South Yorks were arrested.
At least two vehicles were involved, an ATV and a Landrover. The ATV team were lamping and working the dogs. They did not have permission to drive all over fields and crops. Ten deer carcasses were found, some lying on the brink of a ditch whilst the others had been thrown into the water. It would appear that the carcasses had been dumped when the poachers realised that the police were closing in on them. The landrover whilst trying to evade the police, was driven into a ditch and the three occupants arrested.
I saw the carcasses, which were mainly Chinese Water Deer and a couple of Muntjac, one of which was a young fawn. Ten deer carcasses, savaged by dogs made a very sorry sight.
With so many similarities to the incident outlined on Hunting Life, it is most likely one and the same. Whether one of the persons arrested actually posted it is a matter for speculation of course. Anyone having any information should consider passing it to Cambridgeshire police.
