The man accused of faking sign language interpretation at Nelson Mandela's memorial has said he was suffering from hallucinations at the time. South African minister Hendrietta Bogopane-Zulu said an investigation was underway into the incident.
The gestures of a man who was supposed to be interpreting the Mandela memorial for deaf viewers was "talking gibberish", according to the principal of a Johannesburg school for the deaf.
Engrid Parken said she had to leave the room because she was so disgusted by what she saw during the service.
Having just met the sign language interpreter from Mandela's memorial, his explanation that he had a schizophrenic attack seems plausible.
Deaf organisations have complained after the man translating the speeches at Nelson Mandela's memorial service 'signed gibberish'.
