just had this from schnews
It is very common for activists to get compensation from the police
in Denmark. If you are arrested and released without charge you can
apply and you can automatically receive compensation (and quite
quickly, unlike in Britain).
This does not apply for the preventative arrests they have been
using, but if you think you have been unfairly treated you still stand
a fair chance of receiving compensation.
