ET has obtained the search warrant and affidavit related to the February 8 incident involving Chris Brown. The document details a play-by-play description of a violent, bloody encounter.

According to the document, Brown was driving his car with a woman identified only as "Robyn F." as his front passenger on February 8 in Los Angeles. Rihanna's real name is reportedly Robyn Rihanna Fenty.

The warrant says that at around 12:25 a.m., Robyn F. answered Brown's phone and read a three-page text message from a previous lover of Brown's. The couple, which has been together for a year-and-a-half according to the document, engaged in a verbal argument that quickly escalated into an alleged violent attack by Brown.

Brown pulled his car over and unsuccessfully attempted to push Robyn F. out of the car, causing her injury as she struck the window, the warrant says.

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.

As a result of the punches, Robyn F.'s mouth began to fill up with blood, which spilled over onto her clothing and the interior of the car, the document says.

According to the warrant, Brown threatened Robyn F., saying, "I'm going to beat the [expletive] out of you when we get home! You wait and see!"

When, according to the document, Robyn F. then placed a call to her personal assistant and she pretended to reveal what happened, Brown said, "You just did the stupidest thing ever! Now I'm really going to kill you!"

The document 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."

As described in the warrant, Robyn F. tried to fight back by attempting to gouge Brown's eyes, and Robyn F. also tried to stop Brown from continuing to drive recklessly, even pulling out the car's key from the ignition and sitting on it.

According to the document, Robyn F. then began screaming for help, and Brown got out of the car and walked away. A neighbor who heard Robyn F.'s screams for help then called 911.
