A source said: "Ryan was allowed to visit, against Redmond’s doctor’s orders, as it was thought the visit would be beneficial to Redmond."
Although Redmond - who was jailed initially following his arrest because the offence marked a breach of probation set following a prior heroin possession conviction - narrowly escaped a prison sentence, friends admitted they are worried being sentenced to the rehab in West Lost Angeles is not enough.

The source added: "Rehab might not be the best fit for Redmond. Rehab is not jail, and there are concerns about the lack of security where he is now. It's not regimented and is run much more loosely than a prison would be. Redmond needs a very strict and secure environment, the last thing he needs is someone sneaking drugs into him … Redmond doesn't grasp that his addiction to heroin could kill him."
