United Australia Party leader Craig Kelly has been egged in a Melbourne park.
A video posted to social media shows a woman smashing an egg on Mr Kelly's head while he sits with supporters in South Yarra's Fawkner Park.
The woman yelled at Mr Kelly to "stop hanging out with Nazis" before calling him an "anti-Semite".
The UAP leader told the woman she was a "disgrace to democracy" and said she should go to jail.
Victoria Police has released a statement saying they are investigating reports a 58-year-old man was assaulted about 1.25pm on Friday.
Police believe two women were involved in the egg-smashing incident.
Mr Kelly was uninjured, police say.
But it's alleged a male cyclist was injured after the car the women were travelling in allegedly ran over his foot.
Officers are yet to identify those involved in the incident.
