Muangthong United F.C.
Hooliganism has begun to cast a dark spell on Thai football especially starting in the 2010s, with several club or international matches were marred with violences. During the 2014 Thai Premier League, the 3–1 victory of Muangthong United F.C. against Singhtarua F.C. sparked violence between the supporters of the two clubs. Another incident involving Thai supporters following Thailand’s victory against Vietnam in the 2015 AFF U-19 Youth Championship hosted by Laos began when they set off signal flares, causing the police to fire a warning shot after they entered the stands to quell the unrest and were met with a violent response. Also after their victory in the 2016 AFF Championship, the Football Association of Thailand (FAT) was fined U$30,000 for failing to prevent the hooligan supporters in their own stadium from setting off flares. Despite its cooperation with police in finding and arresting the hooligans, Thailand has been warned that severe punishment will be given if it happens again at any future FIFA or AFC matches.
