Historically I knew that as when we were in primary school, a boy in my brothers class 2 years below me, killed a little girl and he was tried and sent to borstal. he was just 10 when he went away. My brother said he saw him when he was about 30 out shopping in town with his wife and little baby. (just an aside there) I have also done research into the quarter session records and found young children being tranported and even hung during the 1700s. (another aside). But certainly 37 years ago, when the only computers were in the hands of computer technicians (I saw my first computer in 1977 at the house of a bloke who went on to make millions in the industry) the police records were not put onto a database and since then I am sure only convicted criminals records have been added retrospectively, if at all.
