Rihanna is said to be cooperating with the Los Angeles Police Department in the investigation concerning the incident involving R&B singer Chris Brown, which took place on Sunday and resulted in Brown having been arrested for having made criminal threats.

Currently, more pieces of information are being brought to light, with reports from TMZ having announced that unnamed police sources had revealed Rihanna’s injuries had been massive.

Reportedly, photos of the injuries show major contusions on both sides of the singer's face, with major swelling and bruising, including a split lip and a bloody nose, along with bite marks on one of her arms and several fingers.

According to TMZ, Rihanna initially did not want to be treated at the scene of the incident, still she allowed the police to take images of her injuries before she was taken to the hospital.

For the time being, the Los Angeles Police Department has not given out the name of the woman involved in the Chris Brown incident, by virtue of rules aiming to protect the victims of domestic violence.

Nevertheless, several media outlets have revealed that Rihanna had been Brown’s victim, including the Los Angeles Times.

LAPD did not disclose the location where the victim had been taken in order to receive treatment for her injuries, yet Radar Online said that an unnamed eyewitness had seen Rihanna undergoing treatment at Cedars-Sinai Medical Center on Sunday.

The source stated that Rihanna had been brought through the back entrance on a gurney, guarded by two police officers, at the aforementioned medical institution.
