Horrific pictures have emerged of the bloodied and bruised mother at the centre of a wild brawl which saw a police officer's head smashed against the concrete.
Kayla Potts, 25, and her fiancé Jack Houldcroft, both from Melbourne's south, were charged over the horrific attack on two officers in St Kilda on Sunday morning.
Recently surfaced footage showed the young mother-of-one getting smacked to the ground by an officer after attempting to step in between he and her brother.
The footage appeared to show Ms Potts lunging at the officer, at which point he retaliated with a Mag light torch to the side of her head.
Ms Potts fell backwards and hit the ground after the impact, remaining on the pavement for a few moments.

'I completely reject straight away any suggestion police have acted inappropriately,' Commander Patton said.

Jack Houldcroft (pictured) did not apply to be released from custody on Monday
Previous footage allegedly showing the couple's friend Phillip O'Donnell slamming Senior Constable Darren Shepherd's head into the pavement went viral on Monday.
Senior police described the shocking video as 'animalistic' and the state premier slammed the footage as 'disgusting'.
The Melbourne Magistrates Court today heard that Potts, her brother Trent, Houldcroft and O'Donnell had been attending a 30th birthday party in St Kilda when they got into an argument upon leaving the venue.
A transgender woman intervened in the dispute but Trent Potts allegedly booted the Good Samaritan in the testicles.
Police were called and arrived on the scene just as the group were about to board a taxi.
Trent Potts, who was allegedly wearing a pink shirt, was identified and questioned by Senior Constable Adam McKenzie.
Detective Senior Constable Jacob Laidlaw told the court Potts then broke free and made a run for it.
Senior Constable Darren Shepherd took chase but tripped on the gutter, he said.
The court heard Trent Potts then allegedly shaped up to Mr McKenzie before striking him.
The experienced officer took him down as his partner ran to help.
It was then that police allege Kayla Potts struck Mr McKenzie from behind before the officer struck her with the Mag light torch.

Police allege Houldcroft punched and kicked one police officer as he lay on the ground and 'spear tackled' another cop after he clambered to his feet
The mother of a three-year-old child appeared in court sporting a bandage on her head from the blow.
It was then that police claim O'Donnell attacked Mr Shepherd from behind, slamming his head repeatedly into the footpath.
They further allege Houldcroft punched and kicked Mr McKenzie as he lay on the ground.
He then allegedly 'spear tackled' Mr Shepherd after he got to his feet.
He was hit with pepper spray, but the men fled, leaving Kayla Potts injured on the ground.
She took herself to hospital and was arrested later that day.

Kayla Potts was the only one of the four people charged over the brawl to walk free on bail on Monday
Her brother was caught that night, with footage found on his phone allegedly identifying his co-offenders.
Police continue to search for several other people they believe participated in the brawl.
Senior Constable Laidlow told the court the officer sustained horrific injuries, including a ruptured bicep and suspected fractured cheekbone.
'It's quite a strong case and it's only going to get stronger,' he said.
Kayla Potts was granted bail by magistrate Donna Bakos despite arguments by police she was at risk of committing further offences.
She had admitted to punching the officer, the court heard.
Her partner made no application for bail.
Trent Potts and O'Donnell were remanded in custody and are expected to apply for bail tomorrow.
The four were each charged with two counts of assault police, affray, violent disorder, intentionally cause injury and other assault related offences.
