The fighting began at 6.45pm at the subway station in Norsborg and police were forced to prevent trains on the red line from stopping at the station. Many of the youths ran off in different directions and police feared that weapons were involved.
When some ten police units arrived at the scene the fighting stopped – only to begin again a few blocks away shortly afterwards.
After 45 minutes police had the situation under control.
“A number of people have become bloody, but nobody has chosen to speak to us so there are no suspects either,” said Pernilla Oscarsson, spokesman at Stockholm police.
