A man in his 60s has been arrested by police investigating the felling of the world-famous Sycamore Gap tree in Northumberland.

The landmark, beside Hadrian’s Wall, was cut down overnight on Wednesday.

Northumbria Police said the man was arrested on Friday evening and remains in custody assisting with inquiries.

A 16-year-old boy was arrested on suspicion of criminal damage on Thursday and has since been released on bail, police said.

Det Ch Insp Rebecca Fenney-Menzies said: “The senseless destruction of what is undoubtedly a world-renowned landmark – and a local treasure – has quite rightly resulted in an outpouring of shock, horror and anger throughout the North East and further afield.

“I hope this second arrest demonstrates just how seriously we’re taking this situation, and our ongoing commitment to find those responsible and bring them to justice.”

The tree grew in a natural dip in the landscape near Hexham and featured in the 1991 film Robin Hood: Prince of Thieves, starring Kevin Costner.
