Police in Amsterdam detained up to 200 protesters after hundreds forced their way onto a Microsoft data-centre construction site. Dutch police said the arrests followed an illegal entry onto private grounds after two groups gathered at the building site. Investigators said some of those detained were carrying items that could have been stolen from the site, while others were suspected of damaging property. All suspects are to be questioned. The protest groups included Fossielvrij NL, a public and climate campaign, which aimed to draw attention to the energy used by data centres. Another group, Geef Tegengas, tried to break through fencing in an attempt to enter the Microsoft site. Their campaigns are described as involving blockades of infrastructure such as ports and other facilities, as well as building sites, in connection with opposition to fossil fuels, capitalism, military expansion and large technology projects. Police said officers asked demonstrators to hand over their tools before they were allowed into an area designated for the protest. Despite that, the protesters allegedly pushed onto the construction site by force. The latest status of those detained was not specified beyond questioning by police.
