Family pursuing bear organised burglary (5,2)
I believe the answer is:
break in
'burglary' is the definition.
(I've seen this before)
'family pursuing bear organised' is the wordplay.
'family' becomes 'kin' (synonyms).
'pursuing' is a charade indicator (letters next to each other).
'organised' indicates an anagram.
'bear' is an anagram of 'brea'.
'kin' put after 'brea' is 'BREAK-IN'.
(Other definitions for break in that I've seen before include "Enter forcibly" , "Illegally enter" , "Interrupt - burglary" , "Criminal entry" , "Domesticate" .)
