Accused murderer Oscar Pistorius was involved in an altercation with a fellow patron at a Johannesburg bar on July 12, according to reports.

Pistorius, who is currently on trial for the 2013 shooting death of girlfriend Reeva Steenkamp, was involved in an argument with a man who brought up the murder case at a Sandton nightclub in South Africa, ABC News reported. The incident reportedly took place in the club’s VIP area.

A man named Jared Mortimer claimed that a drunken Pistorius made disparaging remarks about his friends before poking him in the chest, South Africa’s Eye Witness News reported. Mortimer said he pushed Pistorius, who fell to the ground. Bouncers intervened before the situation escalated.

Anneliese Burgess, a representative for Pistorius, confirmed on Monday that an altercation had occurred, but she did not say the argument included physical contact.

“We can confirm that Oscar was at the said venue with one of his cousins," Burgess said, according to ABC News. "They sat in a quiet booth in the VIP section when they were approached by an individual who has now been identified as a Mr. Mortimer. 

“The individual, according to my client, started to aggressively interrogate him on matters relating to the trial," she added. "An argument ensued during which my client asked to be left alone. Oscar soon thereafter left the club with his cousin. My client regrets the decision to go to a public space and thereby inviting unwelcome attention."

The murder trial for Steenkamp’s fatal shooting will resume on Aug. 7, when the prosecution and defense will present their closing arguments. Throughout the proceedings, Pistorius insisted he shot her by accident. If convicted of premeditated murder, Pistorius faces 25 years to life in prison.
