South African investigators search for Gadaffi’s billions

South African officials are investigating claims ex-Libyan leader Muammar Gaddafi and his family stashed one billion dollars in assets in the country.  Libya has reportedly called for help in repatriating diamonds, gold and cash.
Reports quoting Libyan investigators say the assets were being held by four banks and security companies in South Africa.
Some estimates suggest that Gaddafi's total foreign assets could be worth as much as 80 billion dollars. 
Gaddafi was captured and killed as he tried to flee his home town of Sirte during Libya's political uprising in October 2011.  Any assets belonging to him or his family are firmly considered by many Libyans as state-owned property that should be returned
