National Football League tie descends into mass brawl

On 12 November 2017, a mass street-like brawl broke out during a their match against Singapore Armed Forces Sports Association (SAFSA). The incident happened in time added on in the second half when Zulfadhli Suzliman was sent off with SAFSA leading 3-2. The match was streamed “live” over the FAS social-media channel. The contentious free-for-all, which apparently started in the closing stages of the match, was shown to a regional audience, without viewer-censorship with SAFSA and Yishun Sentek players fighting with unstoppable punches and flying-kicks. Yishun Sentek coach, Yakob Hashim said to Straits Time that Zulfadhli told him that Nazirul Islam (from SAFSA) verbally abused his mother and he retaliated with a kick, which led to his red card. Coach Yakob also said that he was paying attention to the both of them when another scuffle involving the reserves broke out at another corner of the pitch. The three FAS match-officials were hapless as the skirmish went about uncontrollably for about 15 minutes as a former Security Branch police officer, immediately alerted the police.
