Paralympic and Olympic runner Oscar Pistorius.

 Johannesburg - A Nike advert of paralympian Oscar Pistorius with the tagline “I am the bullet in the chamber” was removed from his official website on Thursday following a shooting at his home in Pretoria.

The advert shows Pistorius dressed in a green lycra body suit coming off the starting blocks wearing his distinctive blades. The Nike “Swoosh” and its slogan “Just Do It” are shown on the advert.

Earlier, the international sportswear brand declined to comment on its future relationship with Pistorius.

“This is a police matter and is under investigation,” Nike SA spokeswoman Seruscka Naidoo said.

“From Nike we extend our condolences to everyone affected by this.”

Nike is one of Pistorius's five major sponsors. He has appeared in a number of commercials for the company since 2008.

Pistorius's model girlfriend Reeva Steenkamp was shot dead in his home in Pretoria on Thursday morning.

Pistorius is in police custody and will appear in court on Friday.

Nike's website was down on Thursday afternoon. - Sapa
