Police in South Somerset have confirmed arrests were made during the weekend's climate change demo - as the group defends the action and 'unplanned arrests'.
Four people were held after the protest in Yeovil town centre on Saturday.
Half of the arrests were for for aggravated trespass and the other two for criminal damage.
A spokesperson for the group defended the action, saying: "The Extinction Rebellion South Somerset Rebellion Day protest was successfully carried out to plan.
"Different levels of participation in actions of civil disobedience, ranging from meditation sittings in a pedestrian precinct to blocking access to a petrol station on the A30 and from a die-in outside Barclays bank to lock-on’s inside the bank, saw over 100 people actively participate in raising awareness of the climate emergency we face.
"Focusing on the fossil fuel industry, its funding and its influence, the Rebellion Day protesters utilised music and singing, as well as banners and physical actions, to spread their message of the need for change in our infrastructure and social systems.
"The arrests, although not planned, were anticipated by the organisers and the well being of the arrestees was monitored and care taken to ensure they got home from Bridgewater Police Station on release.
"All four were released without charge, pending investigations."
