Brown, 19, was arrested Feb. 8 after allegedly assaulting Rihanna, 21, in L.A. Police presented their case weeks ago, but prosecutors asked for more information.
According to a leaked police search warrant, an argument between Brown and Rihanna ensued after she read a lengthy text message from a woman on Brown's phone.
He allegedly tried to push her out of the Lamborghini and hit her head against the passenger window.
He then punched her while still driving; blood filled Rihanna's mouth, according to detectives.
Brown allegedly told Rihanna, "I'm going to beat the ---- out of you when we get home."
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."
