R&B singer Chris Brown has denied claims he punched a woman who took a photo of him in a Las Vegas hotel.
Police have said they are investigating an allegation of battery against the 26-year-old musician.
Officers received a call on Saturday morning about the alleged attack at the Palms Casino Resort.
The alleged altercation took place in a room at the resort when the victim tried to take a picture of Brown.
Police said the woman told them she was struck by the Grammy winner and that he had taken her mobile phone.

Detectives tried to speak with Brown at his hotel room, but the singer left before police had arrived.
Police have not named the alleged victim, but she was identified by celebrity news website TMZ as a Brazilian model.
Investigators said Brown has been listed as a suspect for misdemeanor theft and misdemeanor battery in the case.
But Nicole Perna, publicist for Brown, issued a statement on Saturday night calling the charges "unequivocally untrue".

The accuser "was escorted out of the private after party at the Palms Casino Resort for being disruptive and out of control", Ms Perna told the AP.
"Once she was in the hallway, while waiting for Chris Brown's security to bring out her phone, she had a total meltdown - throwing her purse to the ground and claiming that she 'could buy everyone in the hotel'.
"Her claim that she had her phone in her possession inside the after party and was able to take a photo causing an altercation with Chris Brown is a complete fabrication," Ms Perna added.
Brown performed on Friday at Drai's nightclub at the Cromwell Las Vegas, where he appears regularly.
