The man accused of faking sign interpretation while standing alongside world leaders like U.S. President Barack Obama at Nelson Mandela's memorial service said Thursday he hallucinated that angels were entering the stadium, suffers from schizophrenia and has been violent in the past.
Thamsanqa Jantjie said in a 45-minute interview with The Associated Press that his hallucinations began while he was interpreting and that he tried not to panic because there were "armed policemen around me." He added that he was once hospitalized in a mental health facility for more than one year.
A South African deputy Cabinet minister, Hendrietta Bogopane-Zulu, later held a news conference to announce that "a mistake happened" in the hiring of Jantjie.
Government officials have tried to track down the company that provided Thamsanqa Jantjie but the owners "have vanished into thin air," said Deputy Minister of Women, Children and People with Disabilities Hendrietta Bogopane-Zulu.
She apologized to deaf people offended around the world for Jantjie's incomprehensible signing, and said an investigation is under way to determine how Jantjie was hired and what vetting process, if any, he underwent for his security clearance.
The deputy minister said the translation company offered sub-standard services, the rate they paid the translator was far below the normal levels and that in order to maintain the interpreter's concentration level, interpreters must be switched every 20 minutes. Jantjie was on the stage for the entire service that lasted more than three hours.
She declined to say who in South Africa's government was responsible for contracting the company that provided the translator, or how those rules could be flouted.
"It's an interdepartmental responsibility," she said. "We are trying to establish what happened."
Jantjie, who stood gesticulating three-feet (1 meter) from Obama and others who spoke at Tuesday's ceremony that was broadcast around the world, insisted in the AP interview that he was doing proper sign-language interpretation of the speeches of world leaders.
But he also apologized for his performance that has been dismissed by many sign-language experts as gibberish.
"I would like to tell everybody that if I've offended anyone, please, forgive me," Jantjie said. "But what I was doing, I was doing what I believe is my calling, I was doing what I believe makes a difference."
The statements by Jantjie raise serious security issues for Obama, other heads of state and U.N. Secretary-General Ban Ki-moon who made speeches at FNB Stadium in Soweto, Johannesburg's black township. The ceremony honored Mandela, the anti-apartheid icon and former president who died on Dec. 5. Many of them, including Obama, stood one yard (meter) away from Jantjie.
"What happened that day, I see angels come to the stadium ... I start realizing that the problem is here. And the problem, I don't know the attack of this problem, how will it comes. Sometimes I react violent on that place. Sometimes I will see things that chase me," Jantjie said.
"I was in a very difficult position," he added. "And remember those people, the president and everyone, they were armed, there was armed police around me. If I start panicking I'll start being a problem. I have to deal with this in a manner so that I mustn't embarrass my country."
Asked how often he had become violent, he said "a lot" while declining to provide details.
Jantjie said he was due on the day of the ceremony to get a regular six-month mental health checkup to determine whether the medication he takes was working, whether it needed to be changed or whether he needed to be kept at a mental health facility for treatment.
He said he did not tell the company that contracted him for the event for about $85 that he was due for the checkup, but said the owner of SA Interpreters in Johannesburg was aware of his condition.
AP journalists who visited the address of the company that Jantjie provided found a different company there, whose managers said they knew nothing about SA Interpreters. A woman answered the phone at a number that Jantjie provided and said it was not for the company, and another phone number went to a voicemail that did not identify the person or company with the number.
Jantjie said he received one year of sign language interpretation at a school in Cape Town. He said he has previously interpreted at many events without anyone complaining.
The AP showed Jantjie video footage of him interpreting on stage at the Mandela memorial service.
