“When we arrived on the scene we found a man with gun wounds,” said Ulf Lindgren of the Stockholm police to daily Aftonbladet.

Police received a call shortly before 2pm on Sunday about alleged gunfire in the area. Witness reports stated that several shots had been fired on the street.

When officers arrived to the scene, just next to a popular local playground, the perpetrator had scarpered and police found one man injured on the road.

According to the police the man was able to communicate with police and he was subsequently taken to hospital for treatment.

One source told Aftonbladet that the man had been injured in his leg, and acid had been thrown over him, but police were unwilling to confirm what had happened or how badly injured the victim is at this stage in the investigation.

However, officers told news agency TT that a forensic investigation is under way.

“We’re now trying to work out what has happened, if there’s more than one perpetrator involved in what has occurred here today,” said Lindgren to TT.

Officers immediately began questioning witnesses and cordoned off large parts of the nearby area.

“What’s vital at this stage is to identify witnesses that have made relevant observations,” Lindgren told TT.

Police have so far not made any arrests in connection with the incident. A preliminary investigation into attempted murder has been initiated.
