AC Milan 's mid-season friendly fixture against Pro Patria at Stadio Carlo Speroni was abandoned after Kevin-Prince Boateng became the victim of racist abuse.
The former Ghana international was dribbling down the flank after 25 minutes of play in front of a section of the stand populated by the opposition's fans.
He then suddenly stopped playing, picked up the ball, and kicked it towards the Pro Patria support, prompting further jeers from the home crowd.
The referee decided to abandon the match a minute later.
