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.
Detectives are now appealing for public assistance to identify a man who allegedly kicked Mr Connolly while he was on the ground.
A police spokesman said officers were monitoring the rally on Roberna Street when the altercation took place.
"An egg was broken on the 69-year-old man’s head by the 17-year-old boy when a scuffle took place and the teenager was taken to the ground by bystanders," a spokeswoman said.
"While the 17-year-old boy was being held on the ground, another male has approached and kicked him in the body a number of times."
A picture of a man who police believe may be able to assist with their enquiries has been released.
Police also confirmed both Mr Connolly and Senator Anning were both interviewed and the investigation about the egging remains ongoing.
Senator Anning came under fire in the wake of the Christchurch mosque shootings after publishing an anti-Muslim statement in response to the attacks.
Mr Anning's statement blamed the right-wing terror attack, where 50 people were gunned down while praying, on an increase of Islamic immigration and stated that Muslim people were "not blameless".
The Senate last week overwhelmingly voted to censure Senator Anning for the comments.
Anyone with information regarding the male in the photo is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report at www.crimestoppersvic.com.au.
