The restaurant area surrounding Friends Arena saw at least one violent attack, three mini-riots and a number of smoke bomb attacks.
Following the match in Solna, which AIK won 2-0, one fan was severely beaten in an attack that left him unconscious. According to the police report, the incident occurred outside of a restaurant in the Råsunda area and the male victim had to be transported by ambulance to the hospital. The victim is in his mid-40s and suffered “serious injuries”, police said.
Police also responded to reports that unruly fans threw smoke bombs into one or more restaurants, and officers additionally had to contend with “three violent riots and numerous fights”. Some football fans also reportedly threw rocks at the police.

The police report said that two people were arrested on riot charges, but no arrests had been made for the violent attack on the 40-something male victim or an unspecified separate attack that caused another victim to be transported to hospital.
Violence and riots are not uncommon at Swedish football matches, especially when rivals like AIK and Hammarby face off. An August 2017 match between AIK and Djurgården, another bitter Stockholm area rival, was marred by violent clashes before the action even got underway and ultimately ended with 171 people being held in temporary police custody.
In another incident, an October 2016 derby between Djurgården and Hammarby was suspended and six people were arrested for rioting after supporters threw flares and projectiles at security personnel then climbed the barricades. The referee removed players from the pitch and suspended the game for almost 30 minutes while police worked to end the confrontation.
Scuffles even broke out between supporters of the same teams during an U21 match earlier that year. A month later, Sweden legend Henrik Larsson and his son were targeted by angry fans following a Helsingborg match, after which Zlatan Ibrahimovic recommended violent fans should “step inside an Octagon cage and settle it there” instead.
In 2014, football violence hit a shocking new level when a 44-year-old male Djurgården fan died from head injuries he suffered during a mass brawl between Djurgården and Helsingborgs IF. Hooligans have also attacked players and referees on the pitch, caused fires to break out in the stands and turned their ire on police.
In an effort to try to cut down on the problems the Swedish government has brought in a ban on wearing masks at stadiums.
