A new report details the play-by-play of Chris Brown‘s alleged assault of Rihanna taken directly from a Los Angeles Police Department detective’s notes.

According to the notes, as reported by TMZ.com via Fox 11 in Los Angeles, the altercation began after Rihanna read a three-page text message on Brown’s phone Feb. 8.

After she became angry, Brown tried to force Rihanna out of the car, but couldn’t because she was wearing a seat-belt, according to detective’s notes.Brown became more violent, and then allegedly shoved Rihanna’s head against the passenger window. After she turned to face him, Brown punched her, and continued punching her while driving, the notes continued.

Rihanna’s mouth was filled with blood, which also splattered on her clothing and the inside of the rented Lamborghini they were driving.

According to the report, Brown told Rihanna: “I’m going to beat the —- out of you when we get home. You wait and see.”

Rihanna left a message for her assistant that said, “I am on my way home. Make sure the cops are there when I get there.”

Brown replied, “You just did the stupidest thing ever. I’m going to kill you.” MORE AFTER THE JUMP

The fight escalated from there. According to the report, Brown continued to punch Rihanna, bit her ear and fingers and put her in a headlock, causing her to nearly lose consciousness.

Brown will be arraigned in L.A. court today, and could be charged with any number of felonies, including domestic violence and making criminal threats. (Each carries a maximum of three years in state prison.)

Rihanna and Brown have since reunited. The pair hung out at P. Diddy‘s house in Miami over the weekend, and have been spotted in L.A. together this week.

“It’s not easy to shut off a relationship she invested so much in,” a source close to the “Umbrella” singer tells Usmagazine.com.
