Police are called to an apartment on Södermalm with reports of a man hitting a woman.
A woman called the police headquarters and told the operator that she is being beaten by a man in an apartment.
At the same time as the conversation was ongoing, a police patrol was ordered to the current apartment.
When the patrol arrived at the scene, information emerged that led to the man being arrested, suspected of assault.
There are no reports that the woman needed hospital care.
Police patrols then performed a door-to-door search in the stairwell to document any observations.
