Amakhosi fans already showed an ugle sight earlier this month after threatening to riot at FNB Stadium following the team's 3-0 Absa Premiership loss to Chippa United.
Following last night's semi-final defeat to Ea Lla Koto, where Chiefs went down 2-0, the Soweto giants' supporters stormed the Moses Mabhida Stadium field in an attempt to intercept the players and coaches, before those in the stands began vandalising and looting property.
The PSL have since condemned the fans' actions and are set to launch a full investigation.
