On Saturday, while the senator was speaking to media at a far-right rally in Moorabbin, Melbourne, Connolly - now commonly referred to in the media and online as Egg Boy - smashed an egg on Anning's head.
Footage of the incident shows a young man watching Senator Anning from the sidelines before he starts filming with his mobile phone, and then smashes the egg on the back of the senator's head.
"Police arrested a 17-year-old male from Hampton after he allegedly threw an egg at a 69-year-old Brisbane man at an address in Moorabbin this afternoon during a planned meeting", Victoria Police said.
Calls to Anning's electoral and parliamentary offices went unanswered on Sunday.

But the reaction of Anning and his team has prompted outrage on social media, with the young boy getting physically and verbally assaulted in the aftermath of the incident.
Mr Bidiri said it was "disturbing to see someone in the senate who's meant to be representing my country have that much hate towards people of my faith and people who have come to Australia for a better future".
