Meanwhile his family insists it is a case of mistaken identity.
The US law enforcement bureau said it also intends to conduct fingerprint and
photo-identification checks to determine if 72-year-old Derek Bond is the man
accused of a multi-million dollar fraud in America.
Bristol-based Mr Bond was arrested at gunpoint while in the republic on a wine-tasting tour with his wife.
He is being held in custody in Durban after being detained at the request of FBI officials.
The father-of-three and his family insist it is a case of mistaken identity.
Mr Bond's wife Audrey said: "Of course he's innocent. I've been married to him
for 50 years so I know he's innocent."
But the FBI told the BBC it believed the pensioner was Derek Sykes, a man they are looking for in connection with a telemarketing scheme which defrauded people of millions of dollars.

On Tuesday the Interpol website carried an image of a Derek Lloyd Sykes on its "wanted" page.
Mr Sykes is the same age as Mr Bond, according to the website.
Mr Bond's son Peter said: "He is receiving moral support from family, friends and the

is the wrong man.
"The FBI and American embassy, however, are being less helpful and have not
even bothered to interview him until yesterday because they were not apparently
aware that he was denying the charges, even though he had agreed to

A spokesman for the British High Commission said diplomats had been in contact with Mr Bond and that the South Africans were treating him well.
"We're encouraging the US authorities to bring this to a
"It's frustrating that it's taken so long that he is either positively identified or eliminated," spokesman Nick Sheppard said.
DeAngela Burns-Wallace, a spokeswoman at the US Embassy, said officials were attempting to confirm whether Mr Bond was indeed the wanted man, who also goes by the name Derek Sykes.
"If he is identified as the individual charged with fraud,
then he would be extradited.
"If not, then he would be released," she said.
