Report from suburban GP (4)
I believe the answer is:
bang
'report' is the definition.
(thesaurus)
'from suburban gp' is the wordplay.
'from' indicates the answer is hidden within the clue.
'BANG' is hidden within 'suburban gp'.
(Other definitions for bang that I've seen before include "Sudden noise; fringe" , "Sudden sharp noise" , "Sound of explosion" , "drug injection" , "Explosion; hair fringe" .)
