Kim Kardashian's brother has pleaded not guilty to misdemeanour battery and petty theft charges following an altercation with a photographer outside a West Hollywood gym.

Rob Kardashian appeared in a Beverly Hills courtroom on Wednesday morning (08May13) to address counts he lashed out at a snapper, identified as Kassandra Perez, after spotting her taking shots of him in a parking lot.

She claims he struck her, grabbed her camera and ripped out the memory card.

Los Angeles County Superior Court Judge Marsha Revel allowed the reality TV star to walk free after his plea, despite the objections of prosecutors, who had asked that his bail be set at $21,000.

Ironically, Kardashian was represented in court on Wednesday by Robert Shapiro, the lawyer who teamed up with his late father to defend O.J. Simpson in the fallen sporting superstar's 1990s murder trial.
