Chris Brown is being investigated for allegedly punching a woman in the face at a Las Vegas hotel early this morning, The Daily News reports. The alleged victim, Liziane Gutierrez, told TMZ that she managed to get her cellphone past Brown’s security into a private party at his suite, and when Brown caught her taking a photo of him, he started yelling and punched her once in the right eye. She claims she then left the party and called the police several hours later, but was not taken to the hospital. Police are currently investigating the incident and have named Brown as a suspect; a representative for Brown says that the accusations are “undeniably untrue.”
