After several deliberations between South Africa Authority and its Zimbabwe counterpart, South Africa government has granted diplomatic immunity to Zimbabwe first lady Grace Mugabe, allowing her to return to Harare and avoid prosecution for the alleged assault of a 20-year-old model, a security source said on Friday.

The source also told Reuters that Mugabe, 52, had failed to appear in a Johannesburg magistrate’s court on Tuesday under an agreement struck with police because of fears she might be attacked.

“There are a lot of exiled Zimbabweans in South Africa,” the source said.
