A pregnant waitress, was knocked down by Robert Jnr as he fled his violent mother who was beating up everyone near her including hotel staff.
It is alleged that the woman fell to the ground and was rushed to hospital, where she later lost her baby.
“She was not hit by Grace. It was Robert jnr who pushed her out of the way as he ran away from his mother”
“Grace did hit staff members … She was hitting everyone – her sons, their friends, the girls and staff members.”
Mrs Mugabe, 52, assaulted model Gabriella Engels a week ago at a Johannesburg hotel where her sons were staying. She has not commented publicly on the case.
South Africa later granted diplomatic immunity to Zimbabwean First Lady Grace Mugabe, allowing her to leave the country without answering questions about the assault allegation.
