This section applies where—
a court is considering the seriousness of an offence under section 28 of the Violent Crime Reduction Act 2006 (using someone to mind a weapon), and
when the offence was committed—
the offender was aged 18 or over, and
the person used to look after, hide or transport the weapon in question (“the person used”) was not.
The court—
must treat the fact that the person used was under the age of 18 when the offence was committed as an aggravating factor, and
must state in open court that the offence is so aggravated.
Subsection (4) applies where the offence is found to have involved the person used's having possession of a weapon, or being able to make it available—
over a period of two or more days, or
at some time during a period of two or more days.
If, on a day during that period, sub-paragraphs (i) and (ii) of subsection (1)(b) were both satisfied, they are to be treated as both being satisfied when the offence was committed.
