Quite, and having a majority population of around 45%, it fits a more general pattern.

Being much larger than Malmö, the distance from a troubled neighbourhood to the nearest calm neighbourhood can be much larger, and that probably helps driving crime rates up.

I think when you have significant segregation and a large minority population (in absolute numbers), minority youth will risk feeling disconnected from and lose respect for the system that is dominated (even if proportionally) by the majority population, and be more likely to chose a path that involves crime. Crime often involves competition, and criminal competition often involves murder.
