A patient is missing from a Dartmouth hospital.

Nova Scotia Health says they need help finding 31-year-old Ryan Joseph Trentleman.

He is described as having hazel eyes, brown hair, 6’1 and weighing 198 lbs.

He was last seen wearing glasses, a blue shirt, brown jeans, black baseball hat and black sneakers.

“The patient’s risk to himself and others increases with the length of time he is away from treatment,” says the health authority in a news release.
