SANTA MONICA (KTLA) -- Redmond O'Neal was taken into custody Thursday after allegedly testing positive for drugs while in court-ordered rehab.
A judge revoked O'Neal's probation after receiving a rehabilitation facility indicated O'Neal had accessed a payphone and had drugs delivered to the facility.
Back in August, the 26-year old was ordered to spend one year in an in-patient rehab center and given five years of formal probation after pleading no contest to heroin possession.
The son of actor Ryan O'Neal and the late Farrah Fawcett was already on probation and could have faced up to 3 years in prison.
But the judge agreed to suspend the sentence as long as O'Neal stays out of trouble.
The judge said he would still consider sending O'Neal back to the rehabilitation program if specific conditions are met.
Sentencing is scheduled for Oct. 7.
O'Neal was pulled over August 2 after running a red light, according to Santa Monica police.
According to police, O'Neal consented to a search of his vehicle, at which time officers located heroin and marijuana inside.
After they executed a search warrant at his apartment, police also allegedly found a 9 mm semi-automatic handgun in his apartment.
O'Neal was placed under arrest and booked at the Santa Monica Jail for felony possession of a controlled substance, possession of marijuana in a vehicle, red light violation and for the violation of his probation.
The 26-year-old has been in and out of jail and rehab for years for substance abuse related issues.
O'Neal's mother, Farrah Fawcett, died in 2009 after a long battle with cancer.
At the time of her death, Redmond was temporarily released from jail so he could attend her funeral, then moved into a drug rehab program.
Fawcett left nearly all of her $6 million estate to her son.
She appointed two trustees "to make sure the money supports her son's journey into sobriety, rather than giving him the means to destroy himself," according to her will.Copyright © 2014, Los Angeles Times
