His spokeswoman, Anneliese Burgess, said the athlete was in a quiet booth in the VIP section of a club in Johannesburg's upmarket Sandton district when a man "started to aggressively interrogate him on matters relating to the trial".
An argument ensued in which my client asked to be left alone. Oscar and his cousin left soon afterwards. Oscar regrets the decision to go to a public place and thereby invite unwelcome attention." She added.
Burgess said the individual concerned "has now been identified as a Mr Mortimer". South Africa's Star newspaper named him as businessman Jared Mortimer, who offered a different version of Saturday night's events of and claimed Pistorius was drunk.
Mortimer said he reacted after Pistorius, who is free on bail, made disparaging comments about Mortimer's friends and the family of president Jacob Zuma. "I took that personally because I am very good friends with a member of the Zuma family," Mortimer was quoted as saying.
He added that Pistorius was intoxicated and started getting aggressive. "He was poking me and saying that I would never get the better of him. He was close to my face and at that point I pushed him to get him away from me – and he fell to the ground."
The VIP Room club, was hosting an exclusive birthday party called the Superhero Squad and many of the guests wore superhero costumes. The club's website says it caters to the "nouveau riche" and invites guests to "slip on your diamante dancing shoes or designer suit and dance the night away at the most ostentatious venue in Joburg."
The club manager insisted "everything is being blown out of proportion''. "I was sitting with him [Pistorius] and his cousin at their table. They were there for an hour and there was definitely no 'altercation' as this person is making out. Perry Mermigas reportedly told South Africa's Times newspapars:
"He was chilling with his cousin, nothing more and nothing less. If there was something, like what is being described, we would definitely have got involved. What I can say is that Oscar was at the club and left, like any other normal patrons, after an hour."
Hours after the incident, On Sunday, Pistorius tweeted for the first time in five months, posting a Bible verse, a collage of pictures of his humanitarian work and an extract from Holocaust survivor Viktor Frankl's book Man's Search for Meaning.
