Four men have been arrested in Melbourne following a series of allegedly racist attacks linked to Australia's largest neo-Nazi group. The arrests were made as part of a 'day of action' against the National Socialist Network. The men were questioned over accusations of serious racial vilification and grossly offensive public conduct. The arrests follow incidents of verbal harassment and offensive behavior towards women and refugee supporters. Police have emphasized their zero-tolerance approach to prejudice-motivated crime and intimidation of police officers.
