The girl was crying "hardout" throughout the whole ordeal and couldn't get to sleep last night, he said.

Auckland City Police acting district commander Jill Rogers said incredible teamwork between members of the public and police ensured a potentially devastating incident was resolved quickly and that the child, who was unharmed, was safely reunited with her family.
"This incident could have had a much more disastrous outcome if it hadn't been for the quick-thinking actions of the members of the public who assisted in directing police and we are very grateful for everyone's efforts."
The youths, aged 13 and 15, appeared in the Auckland District Court's youth court this morning on charges of kidnapping, unlawful taking of a motor vehicle, wilful damage and assault with intent to rob.
