Triad thugs running wild (10)
I believe the answer is:
distraught
'wild' is the definition.
(I've seen this before)
'triad thugs running' is the wordplay.
'running' indicates an anagram.
'triad'+'thugs'='triadthugs'
'triadthugs' is an anagram of 'DISTRAUGHT'.
(Other definitions for distraught that I've seen before include "crazy" , "Deeply agitated" , "wild" , "Greatly agitated in mind - hits at drug (anag)" , "Having got the wind up" .)
