Pistorius involved in row at Johannesburg nightclub

Oscar Pistorius's spokesperson says he "regrets" a decision to go out to a nightclub in Johannesburg after getting into an argument with a man about his ongoing murder trial.

Anneliese Burgess said Pistorius was in a "quiet booth" at the VIP Room with his cousin on Saturday night, days after the athlete's trial was adjourned until August 7, when he was "aggressively engaged" by a stranger.

The man, identified by South African media as Jared Mortimer, claims Pistorius was drunk and had insulted him before he pushed him back into a chair as bouncers intervened.

But a spokesperson for the club denied the incident, saying: "(Pistorius) was there but there was no altercation and if there had been, we would have known about it."

Ms Burgess said Pistorius left shortly after the argument and "regrets the decision to go to a public space and thereby inviting unwelcome attention".
