Llyn Brenig ospreys: CCTV shows moment vandal takes chainsaw to nest
The moment a vandal took a chainsaw to a platform with an osprey nest on top has been captured on CCTV.
Police said the protected bird of prey had laid its first egg a day before the nest was felled at Llyn Brenig, which borders Conwy and Denbighshire.
It has been branded a "horrific act of vandalism" by the Brenig Osprey Project in a Facebook post.
PC Dewi Evans from North Wales Police's rural crime unit said the act would have a significant impact on what had been a conservation success story
