The details come after Mugabe said last month his wife had made an "emergency” trip to South Africa to find "secure accommodation" for their two sons.
Robert Junior and Chatunga Bellarmine had been renting a luxury apartment at the pricey Regent apartment hotel, in Morningside, Sandton where the average rent goes as high as R74 000 per month.
"There were almost daily complaints by other tenants about the noise coming from apartment 601 of the Mugabes'. Things however came to a head late last month after "a violent brawl" in the complex's entrance area left a member of the boys' security team seriously injured.
The fight was said to have involved "a dispute over women" and the boys were forced to vacate the property after that incident.
Mugabe's sons relocated to South Africa from Harare and Dubai earlier this year.
The First Lady's trip to South Africa last month meant that she missed a rally to drum up support for her husband's 2018 re-election bid. It was at that rally that Mugabe first told supporters about his sons' accommodation "emergency", although he gave no details.
The students at the University of Johannesburg were chauffeured around in luxury limousines with security details.
