The Los Angeles district attorney has reportedly asked police detectives to dig up more evidence as they build their case against singer Chris Brown.
The police are getting cooperation from Rihanna, Brown's alleged battery victim, and what she has told them so far is even more chilling than presumed.
E! News reports that Rihanna has alleged to police that Chris Brown not only inflicted horrific injuries on her, but choked her while threatening to kill her.
She says she lost consciousness in the midst of this.
The couple is said to have been squabbling after leaving Clive Davis' pre-Grammy Awards party late Saturday. Shortly after midnight, things blew up.
Cops say a message from a woman who wrote about hooking up with Brown may have played a role in triggering the argument. However, there's also a reference in the police report to an argument over a rapper, but this is NOT the woman who texted Brown.
In any case, Chris Brown pulled his rented Lamborghini to the side of a street in L.A.'s Hancock Park area. That was when Rihanna allegedly grabbed the car keys and tossed them out the window, sending Brown into a blinding rage.
Rihanna's account of her assault by Chris Brown is disturbing to say the least.
He tried in vain to find the keys, then came back to the car, put his hands around her neck and, according to the insider, said, "I'm going to kill you!"
According to the source, the 20-year-old "Disturbia" singer told L.A. police investigators that she lost consciousness, and when she awoke, Brown had fled.
Rihanna's right eye was blackened and badly swollen, and she had hand prints on her arms after she regained consciousness.
The responding officers were so concerned about her, they drove Rihanna to the hospital in their squad car instead of waiting for an ambulance.
