Officer to apprehend staff (9)

Ross

I believe the answer is:

catchpole

'officer' is the definition.
(thesaurus)

'apprehend staff' is the wordplay.
'apprehend' becomes 'catch' (I've seen this before).
'staff' becomes 'pole' (I've seen this before).
'catch'+'pole'='CATCHPOLE'

'to' is the link.

I've seen this clue in The Mirror.
