Redmond O'Neal was formerly charged with felony heroin possession today in Los Angeles.

The 24-year-old son of Farrah Fawcett -- who is currently hospitalized with cancer -- and Ryan O'Neal was arrested Sunday for attempting to bring the drug inside a jail in Castaic, Calif.

He remains in custody on $75,000. He will be arraigned on April 24. His attorney did not return calls to the Associated Press.

O'Neal and his father were arrested last September in their Malibu home on suspicion of meth possession.

O'Neal pleaded not guilty to those drug charges on March 25. Ryan pleaded guilty and was ordered into an 18-month drug treatment program.

Fawcett is currently recovering from complications from a medical procedure to treat her anal cancer, which, her doctor announced Monday, recently spread to her liver. =
