Cori Glencross, 23, appeared at the Geelong Magistrates' Court charged with affray, committing an indictable offence whilst on bail, unlawful assault by kicking and unlawful assault.

Senior Constable Shannon Thompson said the assault happened at a bus stop outside the Geelong mall on Tuesday afternoon.

It is an area which has long been the centre of community angst about anti-social behaviour.

He said the victim — an elderly woman who was using a walking frame — was dragged to the ground and kicked twice to the chest.

The victim has not yet been identified by police but is believed to be aged around 70.

The assault was filmed by a friend of the accused and posted to social media.

The video was played twice in the courtroom and, both times, Ms Glencross put her head in her hands as audio from the alleged assault was heard.

Senior Constable Thompson said Ms Glencross was arrested at an East Geelong home on Tuesday night, just hours after the attack, and told police she was initially threatened by the woman.

"She said she was provoked by the elderly lady," he said.

"She declared her actions were an act of self defence."

The court heard Ms Glencross told police she "had no intention of kicking" the elderly lady and it was the result of an epileptic fit.

Ms Glencross refused the magistrate's offer to adjourn the case so she could seek legal representation, and instead represented herself.

She told the court the incident was initially a case of self defence.

"When I was getting her off me I had a seizure and couldn't control my body and it looks like it was on purpose but it wasn't on purpose," she said.

"Since I was in lock-up last time and was granted bail I've been doing a lot better, I've stopped hanging around the mall.

"If I have to go into town it's for an appointment and I get straight on the bus and go straight to where I need to go."

The court heard she had received more than 100 messages — including many threats — and 60 new Facebook requests since vision of the attack was shared on social media.

Magistrate Michael Coghlan said it was "highly improbable" that a court would accept her defence that the actions were due to an epileptic fit.

"This is an extremely serious assault and I am concerned that that has occurred while you have been on bail," he said.

"It seems that you spend some considerable time in the mall.

"That, in my view, would increase the risk of you engaging in this sort of activity again."

Ms Glencross was refused bail and remanded in custody to appear again in court later this month.
