Police raid is disastrous for magazine (10)
I believe the answer is:
periodical
'magazine' is the definition.
(I've seen this before)
'police raid is disastrous' is the wordplay.
'is disastrous' indicates anagramming the letters.
'police'+'raid'='policeraid'
'policeraid' is an anagram of 'PERIODICAL'.
'for' acts as a link.
(Other definitions for periodical that I've seen before include "Publication" , "Newspaper" , "Magazine" .)
