Second, where the exploitation of itself involves the commission of serious criminal offences, the exploitation offence will be especially grave. Third, the number of children whose travel is facilitated or arranged will be of importance. Fourth, the offence will be aggravated if the same child is the subject of travel with a view to exploitation more than once. We note that all of those features are present on the facts of this case."
