Not having worried, put in for global police force (8)
I believe the answer is:
interpol
'global police force' is the definition.
(international police organisation)
'not having worried put in' is the wordplay.
'not having' suggests deleting specific letters.
'worried' becomes 'ate' (something worrying may eat someone up).
'put in' becomes 'interpolate' (to interpolate something is to insert it).
'interpolate' with 'ate' removed is 'INTERPOL'.
'for' is the link.
(Other definitions for interpol that I've seen before include "Multinational crime fighters" , "Lyon-based Police Commission" , "crime unit" , "Forces cooperating" , "investigators" .)
