Redmond O'Neal pleaded not guilty to a felony charge of heroin possession, Access Hollywood has learned.
The charge stemmed from Redmond's arrest on April 5 on suspicion of taking heroin into an LA-area jail facility.
Redmond is due back in court on Thursday for a hearing on unrelated drug charges.
As previously reported on AccessHollywood.com, over the weekend, the 24-year-old, who has been in custody since his April 5 arrest, was granted a three-hour release to visit his ailing mother Farrah Fawcett, who is battling cancer.
