A woman was battered by sick female thugs in a vile attack which they filmed on a mobile phone.
A shock video showed the 24-year-old victim being beaten up inside a house before she runs away into the street.
Merseyside Police said two women have been arrested in connection with the assault on March 2.
A 19 year-old woman from Liverpool was arrested on suspicion of assault, blackmail, theft, criminal damage and racially/religiously aggravated intentional harassment.
A 21-year-old woman has also been arrested on suspicion of theft and assisting an offender.
The harrowing footage, which is two minutes and 19 seconds long, appears to have been taken by a woman who can be heard encouraging the attack, the Liverpool Echo reports.
In the footage, she shouts to the woman carrying out the assault “get her in the face”, “get her right in the back” and “whack her head off the stairs”.
At least three other bystanders appear to be present in the footage and can be seen looking on as the attack takes place with music blaring in the background.
The victim is filmed cowering on the floor in tears as she tries to protect her face by covering it with her coat.
At one point, she tries to get to her feet before she’s kicked in the face and grabbed by the hair.
The woman filming the footage can then be heard telling the victim to say sorry to the attacker before a drink - which is said to have been vodka, is thrown over her.
The sound of smashed glass can be heard in the footage as it’s thrown in the victim’s direction, who says: “I’m going to my mum’s.”
As she gets to her feet and starts to leave the house, the woman filming shouts “get out girl, run, run, run” and follows her outside into the street.
Merseyside Police said the victim suffered non-life threatening injuries.
Detective Inspector Paul Jones said: “We are carrying out a number of enquiries to establish the full circumstances, and I am keen to speak to anyone who has any information.
“If you witnessed the incident, or have any CCTV or dashcam footage, please let us know. Any information, no matter how small, could prove vital to the investigation.”
