In 1968, while supervising the semi-final match between Indonesia XI and Mohammedan Sporting, after a penalty was awarded to Mohammedan Sporting in the second-half, the Indonesians protested and an altercation ensured, the match was eventually abandoned after physical battle between both teams.
"After 15 minutes of play in the second half a penalty kick was awarded in favour of Mohammedan side for handling the ball inside the penalty box of Indonesian side intentionally by a player of Indonesia. I placed the ball on the penalty mark but the Indonesian side started obstruction… and eventually the full team left the ground under the instigation of their Manager and Coach. I then allowed the kick to be taken by the Mohammedan side, but the game could not be restarted as the opponent was absent."
Later on, Mohammedan Sporting were awarded the match and entered the final, where they beat the Ceylon Colts XI, winning the competition.
