Figure can go to criminal (7)
I believe the answer is:
octagon
'figure' is the definition.
(type of geometrical figure)
'can go to criminal' is the wordplay.
'criminal' is an anagram indicator.
'can'+'go'+'to'='cangoto'
'cangoto' anagrammed gives 'OCTAGON'.
(Other definitions for octagon that I've seen before include "Eight sided figure" , "Eight-sided shape" , "Figure of many sides" , "Eight-sided room" , "plane figure" .)
