Mike Kendrick, a close friend of Oscar Pistorius, has described the 26-year-old as a "terribly humble man and very kind person".
In his role as head of the Mineseeker charity, Mr Kendrick has worked with Pistorius - who is the charity's ambassador - for the past ten years.
However, his decision to stand by his friend has led to death threats and "nasty emails and letters" for the Midlands based businessman.
Speaking to Daybreak he said: "I've never seen the other side of [Pistorius] that's been reported he's been a very caring, human individual, great humanity."
He added, "I'm not a judge and jury and while a lot of his sponsors have removed him, he's an ambassador for my foundation and he's done a great job".
Oscar Pistorius is currently on bail after being charged with the premeditated murder of girlfriend Reeva Steenkamp, who was shot dead at his home in Pretoria in February.
Oscar Pistorius' murder trial was adjourned until mid August today after the prosecution requested more time for further investigation.
The parents of Reeva Steenkamp, who was fatally shot by Oscar Pistorius, have spoken of their grief and the questions surrounding her death.
