Blamed unfairly for commotion (6)
I believe the answer is:
bedlam
'for commotion' is the definition.
(I've seen this before)
'blamed unfairly' is the wordplay.
'unfairly' indicates anagramming the letters (I've seen this in other clues).
'blamed' is an anagram of 'BEDLAM'.
(Other definitions for bedlam that I've seen before include "State of extreme confusion and disorder" , "Very noisy confused place" , "Scene of uproar and confusion" , "Chaos - former asylum" , "Blamed for a lot of noise" .)
