The answer is yes. Young offenders are treated, for the purposes of DNA data banking orders by courts, exactly as adults are, and they will be subject to the same designated offences if they're found guilty, as opposed to being convicted. You'll see the various language. But a younger person would be eligible for DNA data banking for exactly the same offences as an adult would be, under exactly the same circumstances, and would have his DNA collected in exactly the same way as an adult would.
There's a distinction in how long it can be retained in the National DNA Data Bank, because as soon as their young offender records are required to be destroyed or the youth criminal justice records are archived, then destruction requirements are separated. So they're not kept in the same system for as long as an adult record, which would be kept indefinitely. That's the only distinction.
