Police have found "no evidence" 15 children who apparently fell ill after eating lollies on a north Queensland school bus were exposed to a toxic substance.
The students, aged seven to 11, started complaining of nausea, abdominal pain and dizziness after arriving at Bluewater State School, north of Townsville, on Thursday morning.
There were fears they had ingested something harmful, but police said there was no indication a criminal offence occurred.
The students underwent toxicology tests and were discharged from hospital on Friday morning.
Earlier on Friday, the bus provider Kinetic said the driver was stood down.
The ABC has contacted them for comment.
