ET has the latest...

Stunning new information is emerging in the dramatic arrest of father and son Ryan and Redmond O'Neal. A source close to the family tells "Entertainment Tonight" exclusively that Redmond's mom Farrah Fawcett was asleep in an upstairs bedroom when the police arrived to conduct a probation search at the O'Neal family home in Malibu.

Twenty-three-year-old Redmond was arrested for suspicion of narcotics Wednesday, along with his father Ryan O'Neal when additional methamphetamine was allegedly found in the elder O'Neal's bedroom.

The source goes on to tell ET exclusively, "The drugs found in Ryan's bedroom were not his. Ryan had confiscated those drugs from Redmond 2 or 3 months earlier, and was only keeping them away from his son. He was being a responsible father."

The police have not turned over the case to the Los Angeles District Attorney as of our publishing deadline. Stay with ET for all the details in this on-going case of Ryan and Redmond O'Neal's double-arrests.
