The man was known to police but officers are remaining tight-lipped about what happened in the run-up to the killing. Police say they do not yet have a suspect for the murder.
On Saturday officers will conduct door-to-door enquiries in the area and a forensic examination of the scene will be carried out.
There appear to have been several witnesses to the incident.
“Many people heard the shots and came to the scene,” said Richard Larsson, Stockholm police spokesman, during the night.
