A man in Vasastaden assaults a woman he is in a relationship with.
The woman claims that the man, among other things, has hit her, pulled her hair, tried to kick her, and called her derogatory names.
After a while, the police find the identified man. He is arrested.
The police cordon off the apartment to be able to conduct a technical examination of the crime scene later. The reason for this is to secure evidence for the continued legal process.
