A Chronicle report said that Charumbira was on his way to Harare when the accident occurred.

Charumbira led a group of youths into heckling and booing Grace as she gave her speech during a presidential interface rally in Bulawayo in November.

The incident angered then president Robert Mugabe who spoke at the same rally shortly after his wife, accusing his then deputy Emmerson Mnangagwa of organising and sponsoring the hecklers.

Mugabe vowed at the time to fire Mnangagwa, which he did two days later, in a dramatic move that was seen at the time as opening the way for Grace to succeed him in office.

This, however, failed to materialise as the Zimbabwean army intervened, subsequently leading to the overthrow of Mugabe from power on November 21.
