Angry protesters have burned placards and exchanged abuse in clashes between Reclaim Australia and anti-racism rallies in Melbourne.
At least four people were arrested and dozens sprayed with capsicum spray, which was widely deployed during the four hours of protests yesterday.
Hundreds of police blocked streets in front of Parliament House, separating the opposing groups.
Small groups of protesters from Reclaim Australia and the United Patriots Front were outnumbered by anti-racism protesters representing Rally Against Racism and United Against Islamophobia.
Police say organisers were warned their behaviour was close to crossing the line into inciting hatred, a criminal offence.
