Golden Dawn, which has seen a sharp rise in support during the country’s crippling economic crisis, has condemned the musician’s murder and says it had no involvement in the attack.

The murder of Fyssas, a rapper known as Killah P, triggered protests around Greece and several smaller rallies in European cities, with the main march late Wednesday turning violent.

Party spokesman Ilias Kasidiaris said it had sued Public Order Minister Nikos Dendias for slander.
“We are taking legal action against everyone … who is responsible for this totally libelous attack against a legal political party,” he said.
“We have said from the very start that we condemn this horrendous attack and that it has absolutely nothing to do with our party. You are all liars and slanderers.”
