A nature warden and two walkers claimed they saw a pair of hen harriers shot at Dersingham Bog, near Sandringham, two weeks ago.

A CPS spokesperson has announced today: “Norfolk Crown Prosecution Service has advised Norfolk police there is insufficient evidence to prosecute anyone over the shooting of two hen harrier birds, a protected species, at Sandringham on October 24.”

He added: “The bodies of the hen harriers have not been found and there is no forensic or ballistic evidence. Witnesses also heard unexplained shooting in the area before the three suspects said they were present at the scene, so other people cannot be ruled out. The three suspects, who were interviewed by police, all denied that the birds were killed by them.”
