IFK Norrköping was beaten by 0-5 in the men's Swedish meeting with Häcken a couple of weeks ago.
When midfielder Henrik Castergren steered the 0-3 goal into his own cage, it ran over for a couple of supporters in the away heel.
One of them went down to the field and tore down a billboard, but was tackled by IFK Norrköping's SLO (Supporter Liaison Officer) before he reached one of the players.
- We are not so bad in the table so that we will have our heads cut off, said Norrköping's Jonathan Levi after the match.
Another person is to be investigated
Now the masked IFK supporter has received his punishment.
After an internal investigation and talks with affected parties, Norrköping has decided to shut him down for the rest of the season and the entire next.
Thus, he is barred from visiting matches in the Allsvenskan, Superettan and Swedish international matches arranged by the Swedish Football Association.
Now Norrköping will investigate whether the other person who went down to the forbidden area should also be suspended.
- He may well also have a punishment to expect, but we want to take part in how he experienced things.
First we want to hear his version.
That message should not be far away either, says Johan Schollin.
