Interpolation cut short by the police (8)
I believe the answer is:
interpol
'police' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for interpol that I've seen before include "Cross-border crimefighters" , "crime unit" , "Law enforcers" , "Forces cooperating" , "Organisation for international police co-ordination" .)
