Rihanna has postponed her scheduled concert in Malaysia on Tuesday as Los Angeles police continued their probe of an attack by R&B star Chris Brown on a woman widely believed to be the pop songstress.

Malaysia-based Pineapple Concerts said in a statement on its website that “in light of recent events involving Rihanna” a new date for the concert will be set within two weeks. In Los Angeles, police presented the case against Brown to prosecutors, but were asked to conduct further investigation, said Sandi Gibbons, a spokeswoman for the L.A. District Attorney’s Office.

Police have not publicly said that Rihanna was the victim of Brown’s attack early Sunday morning ahead of the Grammy awards, where they were both scheduled to perform. But unnamed police sources have told the Los Angeles Times that Rihanna was and that she was cooperating with police.

In recent days, her publicist has issued only one statement, which said: “Rihanna is well. Thank you for concern and support.”
Brown, 19, has been arrested and charged with making criminal threats. He is currently free on bail.

The incident occurred in Brown’s car, and celebrity websites and magazines have said Brown left the scene and police found Rihanna, 20, suffering from a bloody nose, split lip and bite marks in the vehicle. She was taken to Cedars-Sinai Medical Center in Los Angeles, but later released.
