Group ready to get caught (4)
I believe the answer is:
sect
'group' is the definition.
(I know that sect is a type of camp)
'ready to get caught' is the wordplay.
'ready to' becomes 'set' (synonyms).
'get' means one lot of letters goes inside another.
'caught' becomes 'c' (cricket abbreviation).
'set' going around 'c' is 'SECT'.
(Other definitions for sect that I've seen before include "Fringe religious group" , "Religious faction" , "Group, faction" , "Breakaway group" , "Cult group" .)
