Athens (CNN) -- The leader of Greece's extreme right wing Golden Dawn party and four party lawmakers have been arrested on charges of forming a criminal gang, Athens police said Saturday. The arrests of the leader, Nikos Michaloliakos, and lawmakers Elias Kassidiaris, Elias Panagiotaros, Ioannis Lagos and Nikos Mihos are part of a crackdown following a controversial stabbing death. At least 10 more people have been arrested, including Golden Dawn party members, police said. More than 30 warrants were issued as police operations were launched across Greece Saturday. One more Golden Dawn lawmaker is still being sought, police said. Pavlos Fyssas, a popular anti-fascist figure and well-known hip-hop artist with the stage name Killah P, was the victim of the knife attack that was allegedly committed by a Golden Dawn supporter.
