"A sergeant and a deputy drove him to his mother's home [Saturday] and he's now back in custody," L.A. County Sheriff's spokesman Steve Whitmore tells PEOPLE.
Whitmore says a temporary release for inmates is common when a family member is gravely ill, to attend a funeral, or similar emergencies. But a source tells PEOPLE that the actress's condition has not changed. Fawcett, 62, is battling cancer.
"Of course she's ill, but nothing should be read into the timing of Redmond's visit," says a source close to Fawcett. "Redmond's attorney had requested that he be allowed to visit his mom a while ago. It was not a crisis or emergency. Farrah is status quo. He had a lovely visit with his mom. Farrah was thrilled to see him. It was a wonderful visit."
The O'Neal family paid $1,285.39 for the visit for personnel and mileage. "The visit wasn't paid for with taxpayer's money," says Whitmore.
Redmond, 24, is currently being held in jail pending a court hearing on April 29. The only son of Fawcett and Oscar-nominated actor Ryan O'Neal will likely receive further drug treatment following his most recent arrest.
A lawyer for Redmond had no comment.
