The police had been made aware of the half-time tunnel incident when the sides met at the Kassam Stadium earlier this month.
However, the police have told The News that their investigation has now been ‘filed’ and will no longer be pursued.
Although it can be re-opened should further evidence/information comes to light.
Both sides meet at Fratton Park tomorrow night (7.45pm) with the Blues seeking to build on a run of 10 points from a possible 12 since that Kassam Stadium outcome.
