Redmond O’Neal has been arrested for drug possession in a prison parking lot.

O’Neal, the son of Farrah Fawcett and Ryan O’Neal, was charged with possession of a controlled substance on jail property, the New York Post reports.

O'Neal was visiting a friend at Los Angeles County’s Pitchess Detention Centre and was detained after a routine security check, during which he admitted to having drugs on his person.

He was charged with two felony counts - suspicion of possession of narcotics and bringing narcotics into a jail.

The 24-year-old is being held on $25,000 bail and will appear in court on Tuesday.

In February, a bench warrant was issued for O’Neal on a missed arraignment relating to a 2008 drug bust involving his father.

His mother, 62, was admitted to the hospital last week and is undergoing treatment for cancer.
