Brown was accompanied by Rihanna, who blew him a kiss as he entered the courtroom. They left together after the short proceeding.
According to prosecutors this week, investigators could not find credible evidence that Brown completed his community labor. Superior Court Judge James Brandlin asked for more information and scheduled another hearing for April 5.
A motion filed Tuesday also raised for the first time in Brown's felony assault case several incidents that prosecutors said demonstrate Brown has ongoing anger management issues. They cited a Jan. 27 fight between Brown and fellow R&B star Frank Ocean, and a 2011 outburst in which Brown threw a chair through a window after he was asked about the Rihanna attack on "Good Morning America."
Brown pleaded guilty to the Rihanna attack and was allowed to serve his 180 days of community labor in his home state of Virginia. The singer spent 1/3 of the hours he logged in Virginia working at a day care center where the singer spent time as a child.
Records said Brown waxed floors or performed "general cleaning" at the center. However, a professional floor cleaner contracted to work at the daycare center told investigators he had been cleaning the floors during the months Brown reported working at the facility.
Los Angeles County Deputy District Attorney Mary Murray stated in her filing that the report on Brown's service was "at best sloppy documentation and at worst fraudulent reporting."
"It did not take long to determine, in what we did in less than 24 hours, that exactly what the D.A. has claimed is absolutely false - and I don't mean just false. I mean fraudulent," said Brown's attorney, Mark Geragos, outside the courtroom Wednesday.
Investigators said they found conflict in the logs recorded by the Richmond Police Department. For example, on Oct. 23, 2010, Brown received credit for eight hours of trash cleanup in Richmond, but the singer's website posted pictures of him participating in a charity event that day in Washington, D.C., which is about two hours away. Brown's lawyer said Brown had plenty of time to get to that event from Richmond.
The Los Angeles County District Attorney's Office wants the court to order Brown to redo his community service in Los Angeles County, where he can be closely monitored.
"Frankly, I'm a little disturbed how the district attorney handled this. It could've handled it much differently," Geragos said.
