The woman, who was snarling after her boyfriend had damaged her car in an argument, got in her vehicle with her sister and chased down her boyfriend and his brother.
When they stopped, the women proceeded to smash up the man’s car with a baseball bat and a steel rod, according to local paper Sydsvenskan.
The woman then turned to her partner’s brother and attacked him. She knifed him in the throat and beat him over the head with a blunt implement, reports the paper.
However the wound to the man’s throat was only superficial.
The women then scarpered from the scene before the police arrived. Well there, the officers were able to patch up the bleeding man. The incident has been classified as attempted murder.
When the angered woman returned to her home, which she shares with her parents and her sister, officers were waiting for her.
In the house, police had made a surprising discovery, finding it contained a fully-functioning liquor store, complete with stacked alcohol bottles and cans, price tags, and price lists.
In the woman’s car they also found a list of orders, according to the paper. The whole family is now under suspicion for breaking Sweden’s alcohol laws.
The 20-year-old woman was arrested on Saturday night. A warrant has been issued for her sister’s arrest, although she is still at large, according to Sydsvenskan.
