A South African government minister has said the company that supplied the sign language interpreter for the Nelson Mandela memorial ceremony has "vanished".
The interpreter who is accused of using fake hand signals at the service on Tuesday has said he suffered a schizophrenic episode.
Deaf organisations in South Africa said he had been signing "gibberish" and complained that he was a fraud.
Hendrietta Bogopane-Zulu, Deputy Minister of Women, Children and People with Disabilities, said that the interpreting company had been providing "sub-standard services" for some time.
