Though there are yet to be any named sources, it does seem pretty clear at this point that Rihanna was indeed the victim of the beating for which Chris Brown was arrested Sunday evening and charged with felony domestic assault.  Plenty of details are now emerging, but they have yet to be confirmed by clearly identified sources.

TMZ listed a vague cite of “law enforcement sources” in their report on the extent of Rihanna’s injuries:

Law enforcement sources have now gotten specific with us… police took pictures of Rihanna’s injuries and they are “horrific.”

As we reported, the photos show major contusions on both sides of the singer’s face — there is serious swelling and bruising. Her lip is split and her nose bloody. We have now confirmed there are bite marks on one of her arms and on several fingers.

And we now know this… Rihanna claims Brown struck her with his fists and that’s what did the damage. There was no object used in the alleged attack.

Rihanna refused treatment at the scene, but before she left cops took photos. We’re told the photos alone are “devastating proof of abuse.”

And we’ve learned it was not Rihanna who called 911. Someone in the area heard her screams and called.

The NY Daily News cited an equally vague “police source” describing Rihanna’s cooperation with the LAPD:

Rihanna is providing “ongoing” cooperation with detectives, who are building a domestic violence case against Brown, a police source told the Los Angeles Times.

A key to the case could be a witness in Los Angeles’ affluent Hancock Park neighborhood who called 911.

Brown, 19, and Rihanna, 20, started fighting inside his car, got out and continued arguing on a block of million-dollar homes.

“The screaming woke up my neighbors, but I slept through it,” said Leslie Erika Klein, 62, who lives on the block. “My son saw them tow away the silver Lamborghini.”

“I hope she’s okay,” Klein added. “It’s a shame.”

Okay, look… I’m not quite sure how to put this without accidentally insinuating something, which is not my intention at all.  I am not remotely alleging that this incident didn’t happen; I would merely like to point out that it took place just two days ago and thus far, the single identified source is an old lady who slept through the disturbance and says that her son told her he saw a car get towed away.  The only described witness (the person who called 911) has yet to be named.

Basically, while the interwebs are all a-flutter with scuttlebutt, I just want to be the boring one who reminds you that these details are still just rumours until confirmed by someone — anyone at all, really — directly connected in any way with the events in question.
