Criminal collared by big match (5,5)
I believe the answer is:
local derby
'big match' is the definition.
(I've seen this before)
'criminal collared by' is the wordplay.
'criminal' is an anagram indicator.
'collared' with letters rearranged gives 'localder'.
'localder'+'by'='LOCAL DERBY'
(Other definitions for local derby that I've seen before include "in which emotions run high" , "Match between two close sides?" , "Meeting of neighbours" , "big match" , "Competition between two close teams" .)
