Wreckage found in Harbourside, Bristol (6)
I believe the answer is:
debris
'wreckage' is the definition.
(I've seen this before)
'in harbourside bristol' is the wordplay.
'in' indicates a hidden word.
'DEBRIS' is hidden in the letters of 'harbourside bristol'.
'found' is the link.
(Other definitions for debris that I've seen before include "Refuse, litter" , "Scattered remains" , "Scattered broken pieces, rubble" , "Brides (anag) - bits and pieces" , "Rubble, heap of broken pieces" .)
