Aberdeen fans claim Boruc made gestures towards their section after Stillian Petrov put Celtic 2-1 in front.
The Police are also investigating an incident in the match where Neil Lennon appeared to be struck on the head by a coin.
Aberdeen fans' complaining is just another example of fans being able to dish abuse out but when something comes their way they spit the dummy. Not much has been said of their constant abuse towards Neil Lennon and Aiden McGeady throughout the match, or the dozens who got thrown out after each of Celtic's goals.
It really is time for them to grow up.
