The man who died is already known to the police.
The 23-year-old is said to have been wanted and is suspected of several crimes, including attempted murder, aggravated weapon crime and kidnapping.
According to sources, he must have been a leading person in the younger grouping of the Södertälje network.
Something that the police currently do not want to comment on.
- For us, this is a serious crime.
We are now focusing on the preliminary investigation and therefore do not want to go into details.
The most preventive measure we can take is to solve the crime, says Mats Åkerwall, police chief.
