Chris Brown will return to jail for a month after being arrested on Friday for violating his probation. On Monday (March 17), a judge cited his "inability to stay out of trouble" as grounds to keep him locked up until April 23. 
 
 Brown, 25, was arrested on Friday based on a warrant issued by probation officials and held without bail until Monday. Though authorities have not yet revealed the cause of the alleged probation violation, TMZ has reported that the singer was kicked out of a Malibu rehab center for violating unspecified "internal rules." 
 
 Brown was ordered to spend 90 days in a residential facility in November for anger-management issues after an incident in which he threw a rock through his mother's car window before being discharged from a rehab facility. Brown spent two weeks in a rehab facility in early October after he was arrested in Washington, D.C., for allegedly assaulting a 20-year-old man. He's due back in court on April 17, when a judge will determine whether he committed criminal assault in that incident. 
 
 Late last month, the Malibu rehab facility revealed in court documents that the singer suffered from PTSD and bi-polar disorder. 
 
 According to TMZ, Brown was thrown out of the Malibu rehab facility for breaking three rules, including one which allegedly applied only to him and which required him to stay at least two feet away from other women at the rehab. 
 
 Brown allegedly violated that rule by touching the elbows and hands of a woman, as well as leaving the facility last week on an unauthorized outing and initially refusing to take a random drug test upon his return. (The tests were reportedly negative, but the initial refusal violated the rehab's rules.) He also reportedly acted out during a rehab group session by making harsh comments. 
 
 The judge in Brown's probation violation case, Superior Court James R. Brandlin, revoked Brown's probation in December, but turned down a prosecutor's request in February to jail the singer again because of the D.C. assault case. Brandlin said at the time that Brown appeared to be making progress in rehab and a probation officer seconded that emotion during by presenting a favorable report during a court hearing on February 28. 
 
 Brown was slated to finish his probation in August, but with a reported 750 hours of community labor left to complete and possible additional penalties for not completing rehab it's likely his probation could be extended once again. ||||| Chris Brown You Got Too Close to Our Women So We Booted You from Rehab

 Brown has been in court-ordered rehab for the past four months 
 
 He is serving five years probation for the beating of Rihanna 
 
 Details were not immediately available about why Brown, 24, was kicked out of the Malibu facility where he has been treated for the past four months. 
 
 Nor was it clear exactly why he was taken into immediate custody, but he had been serving a five-year probation sentence when he entered rehab. That sentence stemmed from a 2009 assault on then-girlfriend Rihanna. 
 
 He was "cooperative when taken into custody" as he was picked up from the facility and taken to the Los Angeles County men's central jail where he was being held without bail Friday afternoon, a sheriff's department statement said. 
 
 His lawyer and representatives did not immediately respond to CNN calls for comment. 
 
 Brown's legal troubles began five years ago when he beat Rihanna as the two were in a rented Lamborghini on a Hollywood street. He pleaded guilty to felony assault in June 2009, which resulted in a sentence of five years of probation and 1,400 hours of community labor. 
 
 The judge has revoked Brown's probation twice in the last year, most recently because of his arrest on a sidewalk near the White House after allegedly punching a man. 
 
 Brown voluntarily entered a rehab program a day after being released from a Washington jail in October, but he was kicked out a few days later for "throwing a rock through his mother's car window" after a family session at the center, a probation report said. Brown was upset because his mother said she wanted him to stay in treatment, the report said. 
 
 "Mr. Brown preceded to walk outside and pick up a rock and threw it through his mother's car window and it shattered," according to letter from the rehab center included in the probation report. 
 
 His probation was revoked last November, but the judge allowed him to stay out of jail by entering a 90-day anger management and drug rehab program. Although he completed that program last month, the judge ordered him to remain a resident at the Malibu treatment facility until another hearing on April 23. 
 
 Brown's probation officer reported at a hearing last month that the singer "continues to make great improvement" in dealing with anger, stress and drugs, but the judge decided he could not go free until after his trial for an assault charge in Washington on April 17. If he is convicted in that case, the judge would decide at an April 23 hearing if Brown should complete his probation in jail. 
 
 Brown has been working on a highway cleanup labor crew in Los Angeles three days a week to fulfill the 750 hours of service remaining in his probation requirements, his probation report said. At that rate, Brown could complete the labor in mid-October and possibly be free from probation requirements by the end of the year.
– Chris Brown was kicked out of a Malibu rehab facility last week, and TMZ says it knows why. First off, he violated a rule specifically imposed on him because he assaulted Rihanna: to keep at least two feet away from all women (he touched a woman's hands and elbows). The other violations? He went on an unauthorized outing last week and refused a drug test when he returned, and disrespected a group-rehab session by making "harsh comments." Now, because rehab was a mandatory part of his probation in the Rihanna case, the singer is back in jail—and MTV reports that a judge today ordered him to stay there for a month due to his "inability to stay out of trouble."
