Nelson Mandela memorial signer checked into psychiatric hospital But it seems the aftermath of his flawed interpretation at the service may have become too much for Mr Jantjie, as a standard check-up on Tuesday ended in the interpreter being admitted to the psychiatric hospital. Mrs Jantjie said: "The past few days have been hard. We have been supportive because he might have had a breakdown. Mr Jantjie stood on stage next to world leaders and Mr Mandela's family on December 10 while speakers addressed the thousands of people in the FNB stadium. Experts said his sign language during speeches from speakers including US President Barack Obama was little more than "flapping his arms around." The White House has since refuted claims that there may have been any danger to Mr Obama's safety. Mr Jantjie blamed his failure to deliver appropriate interpretation on a psychiatric episode, claiming he had seen angels coming into the stadium. The African National Congress (ANC) said it had used Mr Jantjie several times in the past and "had not been aware of any complaints regarding the quality of services, qualifications or reported illness" of the interpreter. Hendrietta Bogopane-Zulu, the South African Deputy Disability Minister, has since said the company which employed Mr Jantjie had "vanished."
