Enraged Chris Brown allegedly punched girlfriend Rihanna and bit her ear and fingers as he drove during a high-speed row on 8 February (09), according to a search warrant and affidavit obtained by a U.S. news show.
Identified as Robyn F, Rihanna reportedly fell victim to her boyfriend's rage after discovering a three-page text message from Brown's unnamed ex-lover.
The police report, obtained by Entertainment Tonight, reveals the couple engaged in a verbal argument that quickly escalated into an alleged attack by Brown, who is preparing for an arraignment hearing in Los Angeles as WENN goes to press.
The Kiss Kiss singer is said to have pulled his rented car over and attempt to push his passenger out, causing her injury as she struck the window.
The document goes on to say that Brown repeatedly punched Robyn F in the face with his right hand, while continuing to drive and steer the wheel of his car with his left hand.
He then threatened her life, stating, "I'm going to beat the s**t out of you when we get home! You wait and see," according to the report obtained by the news programme.
The document suggests Robyn F then placed a call to her personal assistant and pretended to reveal what happened, prompting Brown to protest, "You just did the stupidest thing ever! Now I'm really going to kill you!"
The report goes on to say that Brown repeatedly punched Robyn F. while he drove, bit into her ear and her fingers, held her in a head lock and applied pressure to arteries in her neck, making Robyn F. "unable to breathe" and begin to "lose consciousness".
The passenger tried to fight back and also attempted to stop Brown from driving recklessly, even pulling out the car's key from the ignition and sitting on it.
According to the document, the passenger began screaming for help, at which point Brown got out of the car and walked away as a bystander called the police.
Brown was arrested and charged with making criminal threats. He faces four years behind bars.
Photographs of the bloodstained upholstery of Brown's rented Lamborghini were leaked to select media on Wednesday (04Mar09).
