Chris Brown has been ordered to stay in jail until a hearing on April 23 following his arrest at a California rehab centre on Saturday.

The stint behind bars will be Chris Brown’s longest and is more than five years after he attacked Rihanna.

Reasons for Chris Brown’s dismissal from the Malibu facility were detailed in court on Monday.

Superior Court Judge James R. Brandlin said he was troubled by a comment Chris Brown made during a group therapy session.

“I am good at using guns and knives,” the rehab centre reported Chris Brown had said in response to an exercise asking him to reflect on what he was good at or excelled at.

Rehab workers also said Chris Brown ignored a worker who was waiting to give him a drug test and that he rubbed elbows with a woman when he had signed an agreement to stay at least two feet away from all female clients.

Outside court, Chris Brown’s lawyer described the singer as having had a bad day at the facility and said he didn’t think his client should be forced to stay behind bars for another month.

He said he planned to petition to have Chris Brown released before the hearing in April.

Police officials in California said Chris Brown co-operated with officers when he was arrested at the Malibu treatment facility.

Chris Brown had been ordered to remain there for anger management treatment.

In November, the singer was sentenced to three months of in-patient rehab.

That was recommended by probation officers overseeing him after he was punished for the attack on then-girlfriend Rihanna before the 2009 Grammy Awards.

A letter from the facility in January stated that Chris Brown was also being treated for bipolar disorder, post-traumatic stress disorder and past substance abuse.

The probation for the Rihanna assault had been scheduled to end this year, but a judge revoked it last year after he was arrested on an assault charge in Washington DC. That case is still pending.
