Wrongly blamed for mayhem (6)
I believe the answer is:
bedlam
'mayhem' is the definition.
(I've seen this before)
'wrongly blamed' is the wordplay.
'wrongly' indicates anagramming the letters (I've seen this in other clues).
'blamed' is an anagram of 'BEDLAM'.
'for' is the link.
(Other definitions for bedlam that I've seen before include "Blamed for chaotic situation" , "Blamed for pandemonium" , "Blamed for deafening noise" , "State of extreme confusion and disorder" , "Blamed for confused uproar" .)
