Police allege Kielan Meddick, 25, had a verbal altercation with a man in Fitzroy at about 11pm on November 18.

The man allegedly threw a spray can towards her as she tried to flee, inflicting an injury. Ms Meddick was treated in hospital.

She alleged it was politically motivated, but police have not confirmed this. Her father is an Animal Justice Party MP.

After a public appeal, the 20-year-old man attended a police station about 2.15am on Thursday.

He was interviewed by police and was charged with recklessly causing injury and discharging a missile.

The Maribyrnong man was bailed to appear before Melbourne Magistrates Court on April 29.

Mr Meddick said he was relieved charges had been laid.

"This has been a difficult time for my family, particularly Kielan, who has struggled greatly since the attack and the abuse that followed after," he said in a statement.

"This matter is now one for the court, and in order to not impact the process, I'll await until it's completion before making further comment."
