TMZ identifies the woman as Liziane Gutierrez, who claims she attended a private party in Brown’s suite in Palms Hotel, Las Vegas.
The alleged victim states that she snuck her mobile phone in the suite to get a photo with him. After she quickly photographed Brown, he allegedly burst out in anger and punched her once in her right eye.
Gutierrez claims she left the party and called police a few hours after the incident. However, she did not go to hospital.
Las Vegas law enforcement have confirmed to TMZ they are investigating the incident and Brown is the suspect. But, a representative for Brown claims that the event is “undeniably untrue”.
This has not been the first time Brown was involved in an incident of violence. In 2009, he was arrested for assaulting his then girlfriend Rihanna.
In late 2015, Brown was denied entry into Australia for a concert tour due to his history of domestic violence.
