China police ran amok (9)
I believe the answer is:
porcelain
'china' is the definition.
(I've seen this before)
'police ran amok' is the wordplay.
'amok' is an anagram indicator.
'police'+'ran'='policeran'
'policeran' with letters rearranged gives 'PORCELAIN'.
(Other definitions for porcelain that I've seen before include "Jasper, perhaps" , "Fine earthenware" , "Fine ceramic ware" , "fragile goods" , "Translucent pottery" .)
