Swansea City chairman Huw Jenkins says the club wants to "move on" from their ball-boy row.
Jenkins said: "On a personal note I find it remarkable that there is any thought of police action.
"Things are done in the heat of the moment and probably everybody looks back and wishes things had been done differently. We accept how things are and all move forward.
"I want everything to get back to normal as quickly as we can, move on and look forward to our next game against Sunderland."
The FA is reviewing footage of the incident and the Belgian's automatic three-match ban for violent conduct can be increased in "exceptional circumstances".
Jenkins would like to see the investigation dropped.
He added: "That would be my personal feeling but I can't control what others are going to do.
"Speaking on behalf of the club, it's something we'd quickly like to forget."
