The son of slain Adelaide Crows coach Phil Walsh has been banned from leaving his low-security psychiatric facility unsupervised.
Cy Walsh was in September 2021 granted unsupervised day leave from the facility after the Supreme Court found he was mentally incompetent when he stabbed his father to death in July 2015.
The decision to allow him to leave the facility unsupervised came after he was diagnosed with multiple sclerosis and had to seek treatment and rehabilitation.
In 2020, he was permitted to make visits into the community with just one other support person, who could include his mother.
Supreme Court Judge Anne Bampton on Wednesday revoked Walsh's licence to leave the facility unsupervised because of apparent mental health concerns.
She made a detention order forcing Walsh to stay at the facility after revoking his licence.
Walsh is next due in court for a review hearing on April 9.
He was found not guilty of murdering his 55-year-old father at the family's Adelaide home after the court accepted he had undiagnosed and untreated schizophrenia at the time.
