Go in Scotland in criminal group (4)
I believe the answer is:
gang
This clue is a double definition.
'go in scotland' is the first definition.
(Scottish dialect word for 'go')
'criminal group' is the second definition.
(I've seen this before)
'in' is the link.
(Other definitions for gang that I've seen before include "Work, criminal, group" , "Group of friends, criminals" , "Group acting with common purpose" , "Criminal mob" , "Association of criminals" .)
