Nelson Mandela’s eldest grandson and current Member of Parliament, Mandla Mandela, was convicted of assault by a regional court on Tuesday.
Local media reported that this followed an alleged road-rage incident in 2013.
Mr. Mandela, who is also a traditional chief in the Eastern Cape village of Mvezo where his famous grandfather was born, will face sentencing at a date yet to be announced.
Prosecutors had charged Mandla Mandela with assault, and for brandishing a gun at another man.
Local media said the younger Mandela had drawn a gun on a 44-year-old teacher whose vehicle had collided with one driven by a guest of Mandla Mandela’s.
The teacher later had to undergo emergency surgery to remove a blood clot from his brain, local media said.
Mr. Mandela made headlines earlier in 2013 when a judge ordered him to return the remains of three of Nelson Mandela’s children – including those of his father – from a memorial centre.
The centre is dedicated to his grandfather.
He had been sued by more than a dozen of Mr. Mandela’s relatives who wanted the remains returned.
