Justin Bieber has been accused of repeatedly punching a man at a hotel in Ohio.
A police report filed by Rodney Cannon says the pop star and his bodyguards attacked him after a basketball match in Cleveland in June.
It reportedly states the 34-year-old had accused Bieber, who is 22, of taking his sunglasses at the Western Hotel and, following this, the singer supposedly became angry after Cannon took pictures of him.
It said: "The victim (alleged) stated his belief he was punched three times during the whole incident by Justin Bieber.
"The victim (alleged) also stated he believes he was also punched by his bodyguards a couple of times.
Cannon has claimed he went to a hospital in Nevada after the incident to be treated for a head injury and concussion.
A spokesman for Cleveland Police said no person has been charged relating to the incident.
