Singer Chris Brown booked in LA

LOS ANGELES, Feb. 8 (UPI) -- Singer Chris Brown faces a possible felony charge in connection with an incident involving singer Rihanna, Los Angeles police sources said Sunday.

Bail was set at $50,000 Sunday evening as the Grammy-nominated R&B star was booked on suspicion of making felony criminal threats, LAPD sources told the Los Angeles Times. Brown, 19, turned himself in to police Sunday evening at the Los Angeles Police Department Wilshire Division station.

Citing sources familiar with the investigation, the Times said police were investigating the incident as a felony domestic violence case. Law enforcement sources told TMZ police received a call about the incident at 12:30 a.m. Sunday, and arrived to find a woman who claimed Brown, 19, assaulted her during an argument in a car.

Police said in a statement the woman was Brown's girlfriend, the singer Rihanna, whose full name is Robyn Rihanna Fenty, the Times reported. The woman reportedly had visible injuries and Brown was not at the scene when police arrived.

Recording Academy officials announced Rihanna, 20, would not perform as scheduled Sunday at the Grammy Awards. Soul singer Al Green took her spot on the show, the Times said.

TMZ said when it contacted Rihanna's representatives for a statement regarding the incident, a publicist said: "Rihanna is well. Thank you for your concern and support."

A spokesman for Brown's record label did not respond to a Times request for comment on the report.

Rihanna and Brown were nominated for the Grammy for best pop collaboration with vocals -- Rihanna for "If I Never See Your Face Again," which she recorded with Maroon 5, and Brown for "No Air," which he performed with Jordin Sparks. The Grammy went to Robert Plant and Alison Krauss for "Rich Woman."

Rihanna was also up for best dance recording for "Disturbia." The Grammy in that category went to Daft Punk for "Harder Better Faster Stronger."
