LOS ANGELES (WPIX) -- R&B star Chris Brown is set to be arraigned Thursday for the alleged, gruesome beating of girlfriend Rihanna.

The arraignment follows a three-week investigation into the alleged assault that occurred early Feb. 8, officials told the Daily News Tuesday.

An LAPD media spokesperson said that the case was handed over to the District Attorney, but according to the celebrity website TMZ.com, police have yet to present the case to the D.A.

Detective Deshon Andrews, who apparently managed the investigation, declined to answer any questions surrounding the case.

Meanwhile, mediatakeout.com reports that Brown may meet with prosecutors as early as Tuesday. A source told the website the meeting with prosecutors is scheduled in hope of finalizing a plea deal. Brown is expected to be accompanied by his lawyers and girlfriend, Rihanna, the website reports.

It's still unclear exactly what charges Brown, 19, will face, if any.

On Feb 8, Brown was booked for making criminal threats and later released on $50,000 bail the same night. Although police never released Rihanna's name, many have speculated the pop sensation was the anonymous victim involved in the assault that occurred in a vehicle in L.A.'s tony Hancock Park, and later reported to police.

A disturbing photo of Rihanna with bruises and injuries was eventually leaked to TMZ.com, and broadcast around the world, confirming the alleged assault that occurred.

The couple reportedly reunited this past weekend in Miami and staying together at a mansion owned by hip hop mogul Sean "Diddy" Combs.
