Parents and carers could be required to phone the police on their own children if they reoffend while out on bail under the Palaszczuk Government's youth crackdown. The Courier-Mail can reveal how new laws, to be introduced in parliament today, seek to involve caregivers in helping police crush a crime wave being waged by about 400 "hardcore" young offenders across the state. More children will be remanded in custody under a youth justice crackdown. They will be able to require caregivers to promise they will be responsible for the child and make sure they don't break curfews and reoffend before they can be granted bail.
