A man in his 60s has been arrested by officers investigating the felling of the world-famous Sycamore Gap tree in Northumberland, police have said. The tree, next to Hadrian’s Wall, was cut down overnight between Wednesday and Thursday in what detectives have called a “deliberate act of vandalism”. It was made famous in a key scene in Kevin Costner’s 1991 film Robin Hood: Prince of Thieves and was among the UK’s most photographed trees. A 16-year-old boy was arrested on suspicion of criminal damage on Thursday in connection with the incident and has since been released on bail. Northumbria police said the man in his 60s was arrested on Friday evening and he remains in police custody assisting officers with inquiries. DCI Rebecca Fenney-Menzies, of Northumbria police, said: “The senseless destruction of what is undoubtedly a world-renowned landmark – and a local treasure – has quite rightly resulted in an outpour of shock, horror and anger throughout the north-east and farther 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. “Although another arrest has been made, this investigation is still in the early stages, and we would continue to encourage any members of the public with information which may assist to get in touch. “If you have seen or heard anything suspicious that may be of interest to us – I’d implore you to contact us. “I’d also like to remind the public that this remains a live investigation so, for that reason, please avoid any speculation both in the community and on social media. “Any information – no matter how small or insignificant you think it may be – could prove absolutely crucial to our inquiries.”
