LOS ANGELES (CBSLA.com) — A Los Angeles Superior Court judge ruled Thursday that R&B singer Chris Brown will spend at least another eight days behind bars.

Brown is accused of violating his probation stemming from the 2009 assault of on-and-off-and-on-and-off again girlfriend Rihanna.

The 24-year-old singer appeared in court before a judge ordered him back on May 9th for a probation-violation hearing.

Brown was arrested last month after he was kicked out of a Malibu substance-abuse and anger-management facility, where he had been for about four months.

Los Angeles Superior Court Judge James Brandlin said the singer reportedly made troubling remarks during a group therapy talk where he discussed his use of guns and knives.

Brown also ran into foul with the law in October 2013 when he allegedly punched a 20-year-old man who photo-bombed a picture Brown was taking with two female friends outside a Washington D.C. hotel. TMZ reported Brown broke the man’s nose.

Brown pleaded guilty in June 2009 to assault by means likely to produce great bodily injury for assaulting Rihanna during an argument that began about 12:30 a.m. Feb. 8, 2009, after attending Clive Davis’ annual pre-Grammy party.

The singer was sentenced to five years probation, a yearlong domestic violence program — which he completed — and 180 days of community service.

Brown’s probation was first revoked last summer after he was charged with a pair of misdemeanors and an infraction stemming from a May 21 traffic crash in Toluca Lake. Those charges have since been dismissed, despite a city prosecutor’s objection to a “civil compromise” in which attorneys said no money was exchanged between the parties.
