Although an official statement is yet to be released, R&B singer Rihanna postponed a scheduled concert in Malaysia today as Los Angeles police continued their probe of an alleged attack by R&B star & boyfriend Chris Brown.

According to Pineapple Concerts, the Malaysian agents for the Rihanna concert, a new date for the concert will be set within two weeks in light of recent events involving the r&b songstress and her boyfriend.

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.

Brown’s celebrity attorney declined to give a statement.

There is no confirmed report yet from the police if Rihanna was indeed the victim of Brown’s attack on Sunday morning, the same day that Rihanna and Chris Brown were both scheduled to perform at the Grammy Awards. All they said was Rihanna was cooperating with them through the investigation.

Rihanna‘s publicist, on the other hand, has issued only one statement: “Rihanna is well. Thank you for concern and support.”

19-year-old Chris Brown has been arrested for the alleged attack and charged with making criminal threats. He is currently free because of $50,000 bail.

The incident occurred in Brown’s car, and according to reports, 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.

Rihanna and Chris Brown held a back-to-back concert here in Manila last November 16, 2008 and were both spotted shopping in Greenhills and chilling at a bar in Ortigas.

Rihanna is famous for her hit songs “Umbrella” and “Disturbia” and Brown is popular for his chart-toppers “Kiss Kiss” and “With You.”
