With court help, ASBO staggers one fearing confinement (13)

I believe the answer is:

claustrophobe

I'm a little stuck... Click here to teach me more about this clue!

'one fearing confinement' is the definition.
The definition suggests a singular noun which matches the answer.

'with court help asbo staggers' is the wordplay.
'with' is a charade indicator (letters next to each other).
'staggers' indicates anagramming the letters (I've seen 'staggered' mean this).
'court'+'help'='courthelp'
'courthelp' put next to 'asbo' is 'courthelpasbo'.
'courthelpasbo' anagrammed gives 'CLAUSTROPHOBE'.

Can you help me to learn more?

(Another definition for claustrophobe that I've seen is " One fearing confined spaces".)

I've seen this clue in The Telegraph.
