A South African sign language interpreter accused of gesticulating gibberish as world leaders paid tribute to Nelson Mandela defended himself as a "champion" signer on Thursday, but said he suffered a schizophrenic episode during the event.
The interpreter, identified as 34-year-old Thamsanqa Jantjie, told Johannesburg's Star newspaper he started hearing voices and hallucinating while on stage, resulting in gestures that made no sense to outraged deaf people around the world.

"There was nothing I could do. I was alone in a very dangerous situation. I tried to control myself and not show the world what was going on. I am very sorry. It's the situation I found myself in," he told the paper.
He did not know what triggered the attack, he added, saying he took medication for his schizophrenia.
