This is never-ending.
Press release from Norfolk Constabulary:
“A 64-year-old man was arrested on Thursday [4 April] on suspicion of a number of wildlife offences.
It follows a police investigation that was assisted by officers from Natural England and the RSPB.
The bodies of over a dozen birds of prey were recovered from the Holt area.
The man was also arrested on suspicion of breaching pesticide regulations. The man, who is also from the Holt area, has been bailed until 22 May while further enquiries are carried out”.
It’s not clear from this press release what species of dead raptors were discovered, or how they died. The alleged pesticide breach may or may not be connected. Nevertheless, well done to Norfolk Constabulary, Natural England and the RSPB Investigations Team. Good to see this information being released at this stage. Take note, Police Scotland!

I’ll hazard a guess that the culprit has something to do with the game-shooting industry – perhaps a gamekeeper working on a pheasant shoot?
