Berlin police used force to break up a protest taking place inside a bus on Sunday in front of the far-right Alternative for Germany’s (AfD) national headquarters.
A very loud siren was heard from the bus, a police spokesman said. Many residents were unsettled and made emergency calls and complaints to the police, the police said in a post on social media.
The department said it had established the identity of three people involved in the incident.
The bus is well-known as being part of protest actions by the group Centre for Political Beauty, which reacted with outrage to the police action.
“They just smashed the windows, surrounded the vehicle and arrested our entire team!,” the group posted on social media.
“This is so blatant – we are speechless. We are at the AfD election party. The fascists continue to celebrate.”
