Public commotion (5)
I believe the answer is:
scene
'public commotion' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for scene that I've seen before include "Place of an event - of the crime?" , "bit of an act" , "Division of a play" , "Locality; embarrassing emotional display" , "Section of a stage work" .)
