Police want to interview a man who allegedly assaulted Will Connolly, the Melbourne teenager dubbed "Egg Boy" after he smashed an egg on the head of Senator Fraser Anning.

Victoria Police have released an image of a man they wish to speak to as they continue to investigate the confrontation between Senator Anning and Mr Connolly on March 16.

Mr Connolly received an outpouring of support from around the world after he cracked an egg on to the head of the controversial politician at a far-right rally in Moorabbin, in Melbourne's south east, in the days after the Christchurch attack.

The Queensland senator then struck out twice with an open hand at the teenager, who was tackled to the ground by a group of the senator's supporters, including convicted criminal Neil Erickson.
