Fans of Malmö FF and AIK had previously done battle in the Lilla Torg square of the city on Saturday night. They were joined by supporters, known as Ultras, of Helsingborg and Danes from across the water for a brawl which resulted in arrests and 15 brought into custody.
A hotel where fans of AIK from Stockholm were staying was later cordoned off to ensure the safety of the travelling support from the capital.
On Sunday the violence escalated when fans encountered each other again in the popular Ölcaféet bar which is packed with Malmö supporters on match days.
A heavy police presence was soon on the scene to break up the dispute. Helicopters were also dispatched to monitor events from the sky before, during and after the match between the long-standing Allsvenskan rivals.
Officials from Malmö FF football club installed metal detectors for the first time in their history outside the stadium as an extra security measure.
“It’s part of security work that began after an incident against Helsingborg in 2011. We decided on doing this a month ago,” Per Nilsson, the club’s CEO told local paper Sydsvenskan.
Violence between ‘ultras’ of Malmö and Skåne rivals Helsinborg have become increasingly common. Last year, Malmö FF player Simon Thern was the subject of a death threat during a match between the two sides in Helsingborg.
“The information we have is that 2300 AIK supporters have come for the match which is more than for the games against Helsingborg,” added Per Nilsson.
