The home side was 1-0 ahead in the last minute before Chonburi FC’s Thiago Kunha took a long pass and went one-on-one with Ratchaburi FC’s goalkeeper Ukrit Wongmeema.
Ukrit rushed out for a save but ended up at Kunha’s feet. The referee called a free kick right outside the penalty box, but – after a consultation with the linesman – changed his free kick decision and awarded Chonburi FC a penalty instead.
The referee’s decision caused tempers to flare on the sidelines and in the stands, and the brawl started when fans began to file out of the stadium after the game.
Chonburi’s visiting fans were reportedly drunk and lit up firecrackers to celebrate their dramatic draw, with some damaging Ratchaburi fans’ motorbikes and cars parked nearby.
A group of Ratchaburi fans retaliated, damaging the Chonburi fans’ bus and reportedly throwing an unidentified object inside.
The violence escalated and continued until nearly 10pm, with several fans of both teams injured and sent to hospital.
The Thai Premier League has ruled that both teams will be penalised and fined B50,000 each for their fans’ involvement in the brawl, and B30,000 each for damage caused to property.
Ratchaburi FC was fined a further B10,000 because their fans threw objects into the field during the game, but the TPL didn’t go as far as banning the fans from future games.
Both teams were also fined B12,000 for sideline offences, when their staff went outside the tactical box marked beside the team’s substitutes bench.
Chonburi FC’s head coach Wittaya Laohakul, meanwhile, was fined B20,000 and banned from attending the next two games, for castigating the referee after the game.
