'delivering lad' is the definition.
(I've seen this before)

'latest asbo not a worry in the end' is the wordplay.
'latest' becomes 'new'.
'not' suggests deleting specific letters.
'worry in the end' becomes 'y' (I can't explain this - if you can you should give a lot more credence to this answer).
'asbo' with 'a' removed is 'sbo'.
'new'+'sbo'+'y'='NEWSBOY'

Can you help me to learn more?
