Checked before a heist (5)
I believe the answer is:
cased
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">checked before a heist</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for cased that I've seen before include "Covered, protected; checked over (by robber)" , "examined with intention to rob" , "Carefully inspected (for crime)" , "put in a box" , "Reconnoitred (sl.)" .)
