Looked at lecherously (5)
I believe the answer is:
ogled
'looked at lecherously' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for ogled that I've seen before include "Eyed lustily" , "Looked at with amorous intentions" , "Eyed lecherously" , "Longingly looked at" , "Stared at" .)
