CHARGING into a home uninvited, Jordana Langwe grabbed her victim by the hair and punched her face and body repeatedly.
After she was dragged out the front door by a witness Langwe lurked in the victim's yard, eventually launching a second attack.
This time Langwe also used her teeth, latching on again and again while her fists continued to pound a Mackay woman.
In court, Langwe's lawyer put her violent behaviour down to wanting to protect her boyfriend from drugs she believed were inside the victim's home.
The frenzied attack on the Mackay woman at her George St home on June 4 last year led to Langwe pleading guilty to break and enter and two counts of common assault.
The 21-year-old Beaconsfield woman appeared in Mackay Magistrates Court on Thursday, six months pregnant and pleading for leniency from Magistrate Nerida Wilson.
Prosecutor Sheena Hayes detailed Langwe's behaviour on the day in question.
She told the court the victim was so scared after the initial attack she had grabbed a knife and told a 000 dispatcher she was going to take matters into her own hands.
"The defendant has attempted to enter the victim's yard. The victim has phoned 000. While on the phone to 000 the victim has observed the defendant run along the path beside her house," she said.
"The victim ran inside, stated she was scared so she picked up a knife. The victim then told the 000 operator 'If she comes in I will stab her, there will be bloodshed'."
However, she put down the knife and was attacked a second time after walking out her front door.
Police officers caught up with Langwe in George St, arresting her.
Officers also noted bite marks and bruising on the victim's shoulder and neck.
Defence lawyer Phillip Moore said Langwe, who knew the victim as an acquaintance, believed she was acting in the best interests of her partner.
"My client was under the influence of alcohol. She, for one reason or another, believed that there were drugs on the premises, where he (Langwe's partner) was," he said.
Mr Moore said Langwe had one previous offence of violence on her record "but that's quite dated".
He also said Langwe was six months pregnant and had been seeking professional help for mental health and drug issues.
MsWilson said the behaviour was "unacceptable" but she took into account Langwe's timely plea, young age, her mental health and attempts to improve her life.
Langwe was placed on probation for nine months and no conviction was recorded.
