The series of events started after a patient at the hospital left without permission in mid December. Police were called to help locate the patient and several days later, a man with the same description of the escapee was brought back to Graylands by police where he was wrongly identified by hospital staff as the runaway patient. The man was subsequently given a batch of antipsychotic drugs but it caused an adverse reaction and he was treated overnight in hospital. The “real” missing patient eventually returned to Graylands.
