Rihanna 'has not pressed charges' against Brown

Rihanna is reluctant to press charges over her alleged beating at the hands of ex-boyfriend Chris Brown, according to US reports.

Brown was arrested and charged with making criminal threats following an alleged attack on the 'Umbrella' hitmaker after a pre-Grammys party on February 8.

He was freed on bail following the incident. He is due in court in Los Angeles on March 5 for an arraignment hearing.

Police are still gathering evidence on the case but Rihanna has so far not come forward to press charges against her ex lover, according to In Touch magazine.

A spokesman for Los Angeles district attorney's office told the publication: "We do not have enough evidence and there have been no charges filed on the Chris Brown case."

But the spokesman is adamant they will seek justice - even if Rihanna doesn't appear in court to testify.

The spokesman added: "If the state gathers up enough evidence, we will press charges with or without her testifying. It is not up to the victim. She will not have to show up during the arraignment."
