Dhaka, Oct. 1 -- South Africa's ambassador to France, formerly a long-serving cabinet minister, was found dead on Tuesday outside a Paris hotel after the window of his room in the high rise building was forced open, prosecutors said.

Nkosinathi Emmanuel Nathi Mthethwa, 58, usually known as Nathi Mthethwa, had "reserved a room on the 22nd floor whose secured window had been forced open," the office of the Paris prosecutor told AFP.

The body of Mthethwa, a close associate of former South African president Jacob Zuma, was found "directly by the hotel", it added.

A source close to the case, who asked not to be named, said the ambassador suffered from depression and his death could have been suicide.An investigation has been opened.
