The Melbourne teenager was filmed breaking an egg on Senator Anning's head at a political meeting in Melbourne's south-east last month, before he was struck by the Queensland senator and restrained by his supporters.

Senator Anning was speaking to the media after addressing the meeting in Moorabbin about 2:00pm on March 16.

"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 police spokeswoman said in a statement.

Police have released an image of a man they wish to speak to.

Officers have interviewed the teenager and the senator.

"The investigation regarding the initial incident remains ongoing," the spokeswoman said.

Last week the far-right senator was censured by the Senate for a statement he issued following the Christchurch mosque attacks, linking the massacre to immigration.

Senator Anning has refused to apologise for his comments, and defended his actions in hitting the teenager.

"He got a slap across the face, which is what his mother should have given him long ago, because he's been misbehaving badly," Senator Anning said.

A petition calling for Senator Anning to be removed from Parliament attracted more than a million signatures and was tabled in the Senate by Greens senator Mehreen Faruqi while she condemned the comments.

The teenager's lawyer, Peter Gordon, said his client did not wish to take any action against the senator or his supporters.

"He's considered his position fully and he has no plans to make complaints or take any action of his own of a legal nature," he said last month.

In an interview on Channel Ten's The Project last month, the teenager admitted smashing the egg on the senator's head "was not the right thing to do" but pointed to an online fundraiser — originally started to bankroll his legal fees — that has now raised in excess of $80,000.

He has promised to donate all the funds raised to victims of the Christchurch attacks.
