Chris Brown will spend another month in jail after a US judge said on Monday that he was told the singer made troubling comments in rehab about being good at using guns and knives.
The R&B star was arrested on Friday after he was dismissed from a Malibu facility where he was receiving treatment for anger management, substance abuse and issues related to bipolar disorder.
Superior Court Judge James R. Brandlin said rehab officials reported to him that Brown said during a group session: "I am good at using guns and knives."
The facility cited three other violations of its rules, claiming Brown refused to take a drug test, made a statement that alarmed rehab officials and was seen touching the elbow of a female client.
His lawyer, Mark Geragos, said the comment Brown made that prompted concern was: "I'm going to ask my higher power to take away my troubles."
Brandlin rejected a request by Geragos that the Grammy winner be released into a different rehab program.
Brown, 24, appeared in court wearing an orange jail jumpsuit, a sharp contrast from the suits and designer jeans for other court hearings.
The singer has been under court supervision since pleading guilty to the felony assault of his then-girlfriend Rihanna in an attack hours before the 2009 Grammy Awards.
Geragos had requested that Brown be allowed to change into a suit but Brandlin refused.
