Greek police have arrested the leader of the far-right Golden Dawn party, Nikos Mihaloliakos, on charges of forming a criminal organisation.
Warrants have also been issued for a number of other Golden Dawn MPs.
The arrest and warrants come amid anger over the murder on 18 September of anti-racist musician, Pavlos Fyssas.
A man arrested for the stabbing told police he was a supporter of Golden Dawn, though the party strongly denies any link.
