Greta Thunberg was among climate activists detained during a protest against the demolition of a German village to make way for a coalmine.
Thunberg was detained after sitting near the edge of the opencast Garzweiler 2 mine, about 5 miles from the village of Lützerath.
“We are going to use force to bring you to the identity check, so please cooperate,” a police officer said to the group.
Thunberg, who joined the protesters on Friday, was seen sitting alone in a large police bus after she was detained.
Riot police backed by bulldozers removed activists from buildings in the village with only a few left in trees and an underground tunnel at the weekend, but protesters including Thunberg remained at the site staging a sit-in into Tuesday.
