Durban - Police say two people have been arrested and more arrests are imminent after the violence that erupted at the Moses Mabhida Stadium after a Nedbank Cup game when hundreds of fans ripped up parts of the stadium, invaded the field, and seriously assaulted at least one security guard.
Players had to run for the safety of the dressing rooms as the fans swept onto the field soon after the final whistle.
Police responded with stun grenades to disperse the rioters, and television pictures showed riot police storming the field and a white armoured police vehicle racing across the edge of the pitch.
South African Police Services spokeswoman Nqobile Gwala on Sunday confirmed the arrests and said the two people were facing charges of public violence and malicious damage to property.
The violence mainly by Kaizer Chiefs fans followed their team's 2-0 loss to Free State Stars in the semi-finals of the Nedbank Cup competition.
In the most disturbing scenes, a female security guard was set upon by a group of supporters on the field. She lay on the ground as they hit her with plastic chairs. A man then kicked her twice in the head. After the second kick she lay motionless and face down on the grass.
Police spokeswoman Gwala did not say if anyone had died in the violence, saying police had no information yet from stadium or medical authorities on any deaths.
Kaizer Chiefs coach Steve Komphela resigned after the game.
