Redmond O'Neal has been arrested again, Access Hollywood has confirmed.
O'Neal, the son of Farrah Fawcett and Ryan O'Neal, was taken in custody on December 29 on a felony drug charge.
He was in court for a drug related probation violation allegation.
O'Neal was not granted bail and appeared in court on Tuesday, where he gave the judge a handwritten note, which was not read aloud.
He was ordered to return to an in-custody drug treatment center at the Impact Drug and Alcohol Treatment Center in Pasadena for 30 days and is due back in court in 30 days for a progress report.
"The defense, the prosecution, and the treatment team all agreed with the court's order," O'Neal's attorney Richard Pintal told Access.
As previously reported on AccessHollywood.com, O'Neal began rehab at the Impact Drug and Alcohol Treatment Center in September. He was ordered to undergo treatment for one year at Impact.
O'Neal was previously incarcerated at the Pitchess Detention Center in Castaic, Calif. for a January 2008 drug arrest and a probation violation in September 2009.
