Two more men both in their 30s have been arrested in connection with the felling of the Sycamore Gap tree in Northumberland in the United Kingdom (UK).
A sycamore tree on Hadrian’s Wall was cut down in September. Police believe it was done on purpose.
A 16-year-old boy and a man in his 60s who had already been arrested in connection with the incident remain on bail, according to the Guardian.
The 50ft tree was looked after by the Northumberland national park authority and the National Trust.
The tree was one of the most photographed trees in the UK, and was made famous by a scene in Kevin Costner's 1991 film Robin Hood: Prince of Thieves.
It was also a popular spot for hikers and tourists alike, and its loss has been felt deeply by the community.
Detective Chief Inspector Rebecca Fenney-Menzies of Northumbria Police said, "The loss of Sycamore Gap has been a devastating blow to the community, both locally and further afield. It was a truly iconic landmark, and its absence will be deeply felt by many people."
"We are working tirelessly to bring the perpetrators to justice, and I hope that these recent arrests demonstrate our commitment to doing so. I would also like to thank the members of the public who have come forward with information so far. Your support has been invaluable."
The tree has been removed from the site and is being kept at a storage facility by the National Trust.
It is not yet clear what will happen to the tree in the long term, but the National Trust has said that it is committed to finding a way to commemorate its legacy.
