Cricket South Africa said on Monday that it would be investigating an incident in which Proteas spinner Imraan Tahir was "verbally and racially abused".
CSA said Tahir was verbally and racially abused by an unknown man during the fourth One-Day International (ODI) against India at the Bidvest Wanderers Stadium on Saturday.
"Tahir reported the incident to the stadium security, and was subsequently accompanied by two security personnel to identify and to have the man ejected from the stadium," CSA said.
Team manager, Dr Mohammed Moosajee, said Tahir made no physical contact with the offender or any of the children in the vicinity.
"The incident is under investigation with the CSA and stadium security teams," he added.
Moosajee said in accordance with the ICC Anti-racism code, spectators who engage in racist conduct are to be ejected from the stadium and can face further sanctions and criminal prosecution.
