The point is, in this case no child was missing. The Dad took his naughty kid home. Imagine how stretched the police would be if someone reported this every time it happens. Madness.
So basically a 3 year old was playing up, so her Dad picked her up and took her home. And a member of the public called the police because of that. Am I the only who feels that calling the police because a three year old was being naughty is a bit odd?
