JOHANNESBURG, South Africa (AFP) —  The youngest son of former Zimbabwean ruler Robert Mugabe has been arrested after a gardener was shot at his South Africa home on Thursday, media reported.

Police said they had detained two men on charges of attempted murder after the shooting in a wealthy suburb north of Johannesburg.

A police spokeswoman declined to identify the suspects but several South African media outlets reported that one of them was Bellarmine Chatunga Mugabe.

Photographs on the IOL News X feed showed pictures of Mugabe, 29, in handcuffs and being escorted by police.

He is the youngest son of Robert Mugabe, the late Zimbabwe president who was ousted in a 2017 military takeover after 37 years in power.

The gardener was in a critical condition, police said.

“The motive of the shooting is unknown at this stage and police investigations are underway,” Colonel Dimakatso Nevhuhulwi said.

The former president’s two sons with Grace Mugabe, Robert Jr and Bellarmine, sometimes live in Johannesburg where they have a reputation for partying.

In 2019, Grace was accused of attacking an employee at the family home in Zimbabwe with a shoe in 2017.

Nicknamed “Gucci Grace” for her lavish lifestyle, she was also accused of assaulting a model with a power cable in Johannesburg the same year.

Robert Jr, 33, appeared in a Harare court in October last year charged with possession of cannabis, which he denies.
