ATHENS, Greece (AP) — Greek police say the leader of the extreme right Golden Dawn party, Nikos Mihaloliakos, has been arrested on charges of forming a criminal organization.

Warrants for the arrest of another five Golden Dawn parliament deputies have been issued. The police counterterrorism unit is looking for the deputies. More warrants are expected.

The arrests come several days after the killing of a left-wing activist rapper by an alleged Golden Dawn member.
