LA's Fox 11 News was able to get its hands on LAPD detective notes from a search warrant in the Chris Brown case that provides disturbing details on the Rihanna beatd-own.
After Rihanna read a text message on Brown's phone from a woman, he tried to force Rihanna out of the car, but couldn't because she was wearing her seatbelt.
Brown then allegedly slammed Rihanna's head against her window, and when Rihanna turned to face him, he punched her.
The notes said blood spattered on Rihanna's clothing and the interior of the Lamborghini.
Rihanna also called her assistant, according to FOX 11, leaving a message saying, "I am on my way home. Make sure the cops are there when I get there."
Brown then reportedly replied, "You just did the stupidest thing ever. I'm going to kill you," and proceeded to punch and bite Rihanna. He allegedly put her in a headlock so long that she almost lost consciousness.
