Chris Brown back in rehab for throwing rocks at mother's car

A judge has ordered troubled R&B singer Chris Brown to spend three months in rehab after a report said a centre discharged him because he threw a rock through his mother’s car window.

Los Angeles Superior Court judge James Brandlin also added additional rules for Brown in the coming months, requiring him to perform at least 24 hours of community service every week and to submit to drug testing as he deals with anger management issues.
