R&B star Rihanna is cooperating with investigators building a domestic violence case against her boyfriend, the singer Chris Brown, a police source said Monday.

Brown, 20, singer of hits such as "Kiss, Kiss," was sentenced to five years probation and 180 hours of community service for the assault in February on the eve of the Grammy Awards.
