CONCERNS are growing for Colin Bell, 38, who vanished from the grounds of Morisset Hospital eleven days ago.
An extensive land and water search has failed to find any trace of Mr Bell, 38, who has a mental illness and needs daily medication.
Mr Bell's mother, Rosalie Ulrich, has urged anybody who sees him to contact Crime Stoppers on 1800 333 000.
Mr Bell is about 180 centimetres tall, of medium build, with greying brown hair, a beard and moustache.
He has significant light blond streaks in the fringe of his hair.
