It is the primary detention used for climate activists, who will be arrested by the police. The police can detain people for 12 hours, which is called preemptive arrest [2]
The procedure:
1) The detainees will be placed on benches in handcuffs until they will be called to be booked and searched.[3]
2) Then they will be led to the cages (pejoratively called "dog cages" in the Danish media) which can each accommodate 8-10 persons.[3]
3) If police investigation leads to charges the detainee will be transferred to Vestre Fængsel. Otherwise the detainee will be released after the 12-hour period since the arrest has passed.
There will be access to toilet and water. Food can be earned after 6 hours. Due to limited heating possibilities the detainees can be granted a blanket.[2]
A common nickname in the press is the "Climate Prison" [4]
