According to Police reports, Rihanna claims that Chris has hit her in the past and she referred to it as an ongoing and escalating abusive relationship.
When Rihanna first spoke to LAPD she refused to tell them what started the argument that night. We've now learned that it was the result of another woman sending Chris a text message about meeting up later on in the night.
During the argument, according to the police report, she ordered him to drive her home and she "faked a call" to someone, saying things like, "He's dropping me off. Make sure the cops are there," reports TMZ.
This enraged Chris. He then said something to the effect of "You are really fu**ed up now. I'm going to kill you." That's when Chris allegedly began his violent attack with his fists.
At some point during the attack Rihanna took the car keys out of the ignition and threw them outside. He reportedly went outside to look for them, and returned back to the car and allegedly chocked her. That's when she lost consciousness and a witness called 911.
Based on Rihanna's statement and her injuries Chris will definitely face a felony domestic battery charge, but it's unclear at this time whether or not if that's the only charge he'll get because evidence that he made criminal threats against Rihanna is kind of thin.
