A protester who was living in a tree in an attempt to stop it from being chopped down has been arrested on suspicion of aggravated trespass.
Four trees are being felled as Bonn Square is redeveloped
Gabriel Chamberlain set up his makeshift tree house in Bonn Square, Oxford, 11 days ago.
The city council secured an eviction order to force him down, but Mr Chamberlain came down voluntarily after he ran out of water and supplies.
The tree was later felled as part of a £1.5m facelift in Oxford's west end.
The sycamore was the largest of four trees which have been cut down.
The operation sparked protests in Bonn Square from other residents and police have arrested at least two other people.
The trees will be replaced with seven semi-mature robinia pseudoacacia trees.
A council spokesman said Bonn Square was in a key location at the intersection of four major routes.
He said the plan was aimed at making the square more attractive and improving CCTV surveillance.
