The Chilli Boys beat Chiefs 3-0 and ended their hopes of lifting the trophy.
CEO of Stadium Management SA Jacques Grobbelaar put out a notice that they were looking for the fan who was captured by television cameras throwing objects at the team after they lost.
Grobbelaar announced on his Twitter account that the man had been identified and a case would be opened, adding that a reward of R2 000 was offered to anyone who could help find the man.
