Warring groups of activists are expected to face off in Melbourne CBD again this weekend, triggering another massive police response weeks after violence exploded at an anti-immigration march.

Police said their intelligence indicated four separate groups, including some who held far-right and extreme ideologies, could try to confront each other on Saturday.

In a statement on Wednesday morning, police said specialist squads, including the public order response team, critical incident response team and mounted officers would be deployed.

“The role of police on the day will be to maintain public order and prevent breaches of the peace,” police said.
