Farrah Fawcett and Ryan O'Neal's troubled son Redmond O'Neal is back in jail following his arrest on drugs charges last week.
O'Neal, who has been sober for six months after battling drug problems for years, was allowed out on a 24-hour release from a California rehab facility where he has been residing since September.
He was taken into custody on December 29 on a felony charge after displaying odd behaviour upon his return to the facility.
Los Angeles County sheriff's spokesman Steve Whitmore says, "When he came back, he told the program counselors that he had used drugs. He tested positive (for drugs)."
And at a scheduled status update on Tuesday, a judge ordered Redmond back to Wayside Detention Center for at least 30 days to focus on relapse prevention.
He is now facing up to six years in prison, as the latest arrest violates probation terms of a previous drug offence.
Redmond was moved to rehab to continue his fight against substance abuse, after serving time behind bars in connection to a January 2008 drug arrest and a probation violation.
