Container found in Manchester (5)
I believe the answer is:
chest
'container' is the definition.
(I know that chest is a type of box)
'in manchester' is the wordplay.
'in' indicates a hidden word.
'CHEST' is hidden within 'manchester'.
'found' acts as a link.
(Other definitions for chest that I've seen before include "drawers in it!" , "Coffer; trunk" , "Large box used for storage" , "It's enclosed by the ribs" , "Rib area" .)
