Olympic runner Oscar Pistorius went to a nightclub in Johannesburg last weekend with a cousin and was accosted by a man who asked him about his murder trial, reports the Associated Press.
Anneliese Burgess, a spokeswoman for the Pistorius family, said after an argument with the man, Pistorius left the club.
More from the Associated Press:
Pistorius was accosted by "an individual who has now been identified as a Mr. Mortimer," according to a statement. The Juice, a South African celebrity news website, said the man who argued with Pistorius is Jared Mortimer, and quoted him as saying that the Paralympic athlete started the confrontation.
"My client regrets the decision to go to a public space and thereby inviting unwelcome attention," Burgess said.
Pistorius faces 25 years to life in prison if he is found guilty of premeditated murder of his girlfriend Reeva Steenkamp. He could also be given a lesser term if he is convicted of negligent killing or murder without premeditation.
Pistorius' trial resumed earlier this month after a month-long break, after which he was evaluated by a psychologist and three psychiatrists. Mental health experts concluded Pistorius, who also faces separate gun related charges, was not mentally ill during the killing.
Prosecutors allege Pistorius, 27, killed his girlfriend on Valentine's Day 2013 after an argument. Pistorius claims he killed Steenkamp by accident, thinking she was an intruder who was about to attack him.
Final arguments are slated for Aug. 7-8.
