Italian police have ordered the arrests of five members of the Kurdistan Workers' Party (PKK) terrorist group on suspicion of extorting money from Kurdish immigrants to support the group. The investigation was sparked by the beating of a Turkish citizen who has a kebab business near Venice. The five are under investigation for conspiring with the intent of extortion and causing serious injury, with the aggravating circumstance of terrorism aims. Authorities also ordered the search of eight residences in Tuesday's action.
