Chris Brown was back in court on Monday where he again faced the possibility of returning to jail. At a probation hearing in front of Superior Court judge James R. Brandlin, prosecutors said they have enough evidence now from Brown's assault case in Washington, D.C., to prove that the singer violated his probation from his 2009 assault on then-girlfriend Rihanna.

According to the Associated Press, Los Angeles District Attorney Mary Murray tried to have Brown jailed again and called for a full probation violation hearing, which would have allowed her to present the new evidence to Brandlin.

"He continues to pose an increasingly violent danger to society," read Murray's motion, which referred to the singer's alleged assault on a man in the nation's capital on October 27. Brown's lawyer, Mark Geragos, earlier turned down a plea deal in that misdemeanor case because he believes his client did nothing wrong.

Following the D.C. arrest, Brown's probation in the 2009 assault case was revoked, though he was not sent to jail because Brandlin was pleased with the singer's progress in 90 days of court-ordered rehab for anger management. Brown spent 16 days
 in a facility to deal with anger issues before leaving to complete his treatment on an outpatient basis.

In asking for more jail time, Murray's motion also cited an incident in which Brown threw a brick through his mother's car window after one of the anger management therapy sessions. The prosecutor said she brought the new motion because she now has information about the man whose nose was allegedly broken in the attack.

Brandlin turned down the request, however, saying that probation officials told him Brown was making good progress in treatment and should remain in the program. Geragos also said that Brown is making "great strides" and shouldn't have his progress stopped by jail.

E! Online reported that Brown, who arrived with his mother, Joyce Hawkins, and on-and-off girlfriend Karrueche Tran, has completed 109 hours of a 1,000 hour community labor sentence and has passed his last four drug tests.

"I say keep things on a short leash," lawyer Geragos said. "Keep him where he is now ... He is making great strides and all you have to do is look at him, and I've known him for five years. He's as good as he's ever been."

Brown is due in D.C. for a hearing in the assault case on February 20 and was ordered to return to Brandlin's courtroom on February 28 for a progress update.
