During a Taekwondo Olympic event, cuban competitor Angel Matos kicked Swedish referee Chakir Chelbat in the face after he had disqualified him for "taking too much injury time in his 80 kg+ Bronze medal match against Kazakhstan’s Arman Chilmanov."
The President of the World Taekwondo Association, Jin-Suk Yang, has officially banned him for life according to some reports. Referee Chelbat was given stitches in his mouth immediately after the kick.
