With backing from the Finnish Copyright Information and Anti-Piracy Center (CIAPC) the international trade body filed the lawsuit in Helsinki demanding that 'operators of TPB stop facilitating the unauthorized distribution of music and pay compensation to rightsholders'.

Additionally the IFPI is extending block requests to two more ISPs.

CIAPC's Executive Director, Antti Kotilainen said: "This type of inhibition has yielded good results, for example, in Italy, where the The Pirate Bay's popularity has decreased significantly."
