In a shocking incident in Södertälje's Västergård area, a man in his mid-50s was found dead in a stairwell, prompting a murder investigation by local police.

The victim, discovered with a severe head injury, has led to the arrest of a 45-year-old woman found outside the building.

Despite her arrest, police spokesperson Ola Österling has stated that the suspicions against the woman are weak due to the unclear circumstances surrounding the man's death.

A technical examination has been conducted at the scene, and the case has been reported to the prosecutor, who will decide on the woman's detention.

Police are not ruling out the possibility that the man might have fallen in the stairwell, with determining the cause of death as a crucial aspect of their investigation.

The situation remains under investigation, with many questions still unanswered.
