A bus driver is under investigation after children were rushed to hospital after eating sweets covered in a "white substance" on a school bus.
A total of 15 primary school students have been hospitalised in Townsville, Queensland, Australia, prompting the local hospital to activate a Code Brown to deal with an "external emergency".
The students, aged between seven and 12, were treated for symptoms of vomiting, diarrhoea and intestinal pain after they fell ill just after they arrived at school.
