Demonstrations went into a third day on Monday after Mate Ma'a Tonga lost their semi-final game against England at the Rugby League World Cup on Saturday night.
The side's 20-18 defeat came after a controversial call in the match's dying moments, when Australian referee Matt Cecchin ruled a knock-on without consulting a video replay.
But while most Tongan fans have been protesting the contentious call peacefully, others have used it as an excuse for reckless behaviour, as evidenced in the video.
