Chris Brown has branded the District Attorney in his court case a ''racist''.

The R&B star let rip on Twitter last night (22.08.13) after he was sentenced to 1,000 extra hours of community service earlier this month for submitting bogus reports for the 1,440 hours he was originally ordered to complete for assaulting then-girlfriend Rihanna in 2009.

Chris raged on the social networking site: ''N***a done 6 months community service wit police and the DA racist ass crying to the judge that I didn't do it. F**k the SYSTEM! (sic)''

The 24-year-old hot-head went on to slam the American justice system for wasting so much time on his case when there are so many more pressing matters to solve.

He added: ''How about y'all take care of all the homeless kids and families on skid row. Promote helping people that are really f***ed up in your city!''

Chris concluded, ''Family first! The LAW ... last (sic)'', before referring to his latest addition to his graffiti-sprayed car collection, quipping, ''I paint pics of monsters because its a reflection of u bitcha*s n***as and this bitchass system! (sic)''

The X-rated rant comes as a surprise since Chris uncharacteristically remained silent during the hearing on August 16 when the decision was reached.

According to TMZ, Chris' rant is unjustified because the actual Los Angeles County D.A. is an African-American woman.
