It all culminated before Sirius' meeting with Norrköping in the Allsvenskan on Monday when the police banned large flags, so-called overhead flags (OH) that can cover large parts of a grandstand section, to reduce the possibility of smuggling in pyrotechnics, which is what the police want access.

Instead of reducing pyrotechnic use, Sirius fans burned off even more than usual and the grandstand was shrouded in thick smoke.

This as a protest.

- You use methods against the wrong groups instead of going on individually.

The caring fans should not have to leave their flags at home.

It is a very strange measure and it becomes very inflamed which has the opposite effect.

There is a discussion with the police management about a new strategy and it will be incredibly important to take part in, says Mats Enquist, Secretary General of Swedish elite football, Sef, in SVT's Morgonstudion.

Enquist saw the match on location in Uppsala

Enquist was in Uppsala and watched the match.

- Individual supporters are harassed, as it is experienced, who have done absolutely no harm.

They remove thousands from the right to go to football, they remove children and young people who come with flags so that they can be used for smuggling.

These are measures that we do not see anywhere else in the community, he says and noted the reaction from ordinary fans nearby.

- Even ordinary adults who have good jobs sit and are cursed at the police.

It's not a good way to act if you tease an entire arena.

The police use a so-called conditional ladder where clubs can be punished in different stages depending on the seriousness and development.

- You are punished according to this staircase in a very collective way and it becomes disproportionate to what happens.

The lack of dialogue is where the shoe squeezes You must be able to communicate, says Nemrud Kurt, football journalist at SVT.

"The police have an obligation to act"

The police do not oppose the atmosphere, but emphasize that it is security and pyrotechnics that can be dangerous that they want.

- Of course, everyone wants safe, secure and atmospheric sports events.

It is positive with committed supporters and a high mood, but if security can not be guaranteed, the police have an obligation to act, says Anders Ternström, head of the legal unit at police region Mitt.

Enquist calls for the order that prevailed from 2014 to 2017 when the problems that prevailed in the grandstand culture were overcome.

- I hope we can find our way back there, says Enquist.
