D.A. Wants More Evidence In Chris Brown Case

Breaking developments in the investigation into that alleged altercation between Chris Brown and his girlfriend Rihanna.

RadarOnline.com has learned that Los Angeles police detectives from the Wilshire station presented information today to the District Attorney's office. Sandi Gibbons -public information officer for the L.A. County D.A.'S office-- tells RadarOnline.com that they requested further information, and that they will have no further comment.

Translation: No charges yet.

Meanwhile, Los Angeles Police Detective Deshon Andrews tells CNN that he has kept the case file closely guarded and no copies have been made of the original photos and documents in order to keep them from leaking to the media.

As is standard practice, the LAPD is not releasing the 911 call that led to their investigation early Sunday, but Andrews said it mostly recorded the sound of "a screaming woman."

Although Brown has not been charged with any crime, the LAPD , with Rihanna's cooperation, is reportedly building a case against him for domestic violence. Brown is free on $50,000 bail.
