Argentine police have arrested 36 skinheads at an event celebrating the 120th anniversary of the birth of Nazi leader Adolf Hitler, officials say.
The Sunday arrests came after a "prolonged and meticulous investigation," said Daniel Perez, the second in command of the Federal Police unit in charge of investigating hate crimes.
Police broke into the Central Argentine Club, in the town of San Martin, in Buenos Aires province, while a recital was being held by the local chapter of the neo-Nazi group Blood and Honour, Perez said on Wednesday.
Police found Nazi-related material, including flags with swastikas, films and CDs of music with racist and anti-semitic lyrics, Perez said.
Blood and Honour, which is based in Britain, has chapters across Europe and the Americas and is aimed at promoting Nazi ideology.
The arrests are "an important success in the struggle to eradicate these groups of Nazi ideology that are a threat to Argentine society," the Delegation of Israeli Associations in Argentina said in a statement.
Argentina has the largest Jewish community in Latin America.
Two deadly anti-Jewish attacks were carried out in Buenos Aires in the past years: the 1992 bombing of the Israeli Embassy that killed 22 people and wounded 200, and the 1994 bombing of a Jewish community centre that killed 85 and wounded 300.
