Things got heated after Jimmy White was given a warning about his behaviour by a referee.
White took exception to the referee laughing during his 4-0 defeat by Luca Brecel in the second round of the BetVictor Northern Ireland Open.
The 60-year-old was already 3-0 down when referee Ben Williams incorrectly nominated the blue ball instead of the brown after White potted a red in the fourth frame, then laughed at his error when corrected by the player.
