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 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 it is 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.
