The SA National Parks (SANParks) has warned the public about a fraudulent fundraising scam taking place at shopping centres and other public places in the Johannesburg area.
SANParks chief executive officer David Mabunda said he had received reports of people dressed in khaki clothing - similar to that worn by SANParks staff - soliciting donations on behalf of the organisation.
He said the incident reported to SANParks indicated that the fundraisers were "raising money for a major game translocation in the Kruger National Park to prevent them from being poisoned".
"There is no such project currently under way," he said.
Mabunda said SANParks was asking the public not to donate any funds to anybody purporting to be representing the organisation. He said unauthorised solicitating of this nature was illegal, and was also a criminal offence.
"Any one found soliciting funds from the public in this manner must be reported to the authorities," said Mabunda.
He asked the public to report such soliciting to the toll-free national security fraud hotline (0800 60 10 11).
