Bolingoli should have suffered racism from the home supporters' section and now AIK is investigating what has happened.

- We have done an internal investigation to get to the bottom of what has happened or not happened at the stand in connection with the Celtic match. We have concluded that we have received so much that we will continue the investigation. We have people we want to meet and hear, but unfortunately they are the ones we mainly want to meet on a journey right now, says Jens T Andersson.

After the match, Celtic posted a video of what happened, but later took it down and apologized for the language of the film. AIK has taken advantage of this material.

- We use our supporter dialogue to find out who has done what, but we are not a police authority so we cannot get people in the way that the police can to a greater extent. But we try to find out what really happened here and when we can safely ascertain it, we will deal with it afterwards, says Jens T Andersson and continues:

- I want to be extremely clear that AIK takes away from all forms of racism.

What can racism from the stands have for the people involved?

- I probably don't want to say that until we have clarified what has really happened.
