Police are pushing to appeal against the release on bail of more than a dozen alleged young offenders by a Townsville magistrate in one day.
Queensland Assistant Commissioner Mark Wheeler said one of the youths released on Thursday had already breached bail conditions by Friday morning and police would ask that they be returned to custody.
A spokesman for the Office of the Chief Magistrate confirmed 13 young people who appeared in the Townsville Children's Court on Thursday were released on bail.
