A Toronto mental health centre will be reviewing its release conditions for a man authorities had described as "a danger to himself and others" when he went missing this week.

Thomas Brailsford, who was found not criminally responsible in the beheading of his mother five years ago, was reported missing after getting out of a cab on the way to a medical appointment. He was last seen in the area of Jane and Bloor Streets on Thursday.

On Friday morning, police reported that he had been located in the area of Lake Shore Boulevard and Windermere Avenue at approximately 11 a.m. He was spotted by a Toronto resident who alerted police of his whereabouts, police said.

Brailsford, 55, is an inpatient residing at Toronto’s Centre for Addiction and Mental Health (CAMH), on Queen Street West at Shaw Street.

CAMH officials told CTV Toronto that he's under strict conditions including when he can go to medical appointments or leave for other reasons. CAMH said he was escorted by a single staff member at the time of his escape on Thursday.

Officials said his recent behaviour indicated that a single escort would be sufficient.

Dr. Sandy Simpson, the chief of forensic psychiatry at CAMH, said the patient's conditions will be reviewed in light of the escape.

"Clearly in retrospect, he has absconded from that level. That means that we will now step back from the situation and review that and see what we can learn from that," Simpson told CTV Toronto's John Musselman on Friday.

He said staff members will talk to Brailsford about why he chose to leave the company of his escort before deciding what measures should be taken in the future.

An Ontario Review Board report filed in February and obtained by CTV Toronto noted that "Mr. Brailsford continues to present as a significant threat to the safety of the public at this time."

Brailsford also went missing in September of last year, when he was granted a day pass and left the CAMH grounds.

He was located two days after disappearing, on Sept. 11, 2014, and returned to CAMH.

Brailsford was charged with first-degree murder in 2010, after his 78-year-old mother Barbara Starkey-Brailsford was found beheaded in her west-end apartment.

He was found not criminally responsible for her death, and brought to CAMH.
