Police in the heavily migrant-populated Swedish city of Malmö say the two shootings and two separate explosions over the weekend are directly linked to rival gangs.

A total of four incidents and an arrest occurred over the course of the weekend in various parts of the city which has been rocked by gang violence, Swedish broadcaster SVT reports.

The first incident occurred on Friday night in the notorious no-go suburb of Rosengård in which an unknown attacker shot at an apartment in the area.

The shooting is just the latest in the area which also saw an explosion outside the local police station in January, which led to several police vehicles and the facade of the building being damaged.

Also on Friday evening, an explosion occurred outside of a driving school that was so powerful the apartments above the school were partially damaged by the blast according to investigators, although no one was injured.

On Saturday night, another shooting attempt occurred in Rosengård when an individual shot at a local townhouse with what is believed to have been a shotgun. The attack came only an hour after a taxi driver had also been shot in the area.

The fourth attack came on Sunday evening as another explosion went off near the site of the first bombing on Friday. According to investigators, the target was a property that contained a hair stylist among other businesses.

The explosion badly damaged the facade of the building, forcing officers to cordon off the area for several hours.

Police then arrested a 21-year-old on charges of extortion at around 1:40am Monday morning who they believe may have some connection to the attacks.

The weekend of violence comes after the city experienced a mass shooting earlier this year which saw three men shot dead outside of an internet cafe in June. It was later revealed that nearly all of the victims of the shooting were known to be involved in the organised crime scene.
