Embattled R&B star Chris Brown's jail time has been extended to the end of April (14) in a bid to keep him out of trouble until his next court hearing.

The 24-year-old singer was arrested and taken into custody on Friday (14Mar14) after he was asked to leave a Malibu, California rehab facility for reportedly violating the centre's rules.

As a result of his dismissal, lawmakers in California ruled he had violated a court order to complete a rehab stint.

The judge who sentenced Brown after he was arrested and charged with beating up then-girlfriend Rihanna in 2009 initially ordered the singer to live in the Malibu, California rehab facility for 90 days in an effort to sort out his anger issues, but he extended the star's rehab stay earlier this month (Mar14), and instructed Brown to stay put until his ongoing assault case, relating to a fight outside a hotel in Washington, D.C. in November (13), was over.

On Monday (17Mar14), Superior Court Judge James R. Brandlin refused a request to allow Brown to complete rehab at another facility and set a probation violation hearing for 23 April (14).

Judge Brandlin also told the singer and his attorney Mark Geragos that he was concerned about remarks the star allegedly made while in rehab about the use of guns and knives, and ruled Brown should stay behind bars.
