Police deployed around pound arresting rogue for minor sin (10)
I believe the answer is:
peccadillo
'minor sin' is the definition.
(I've seen this in another clue)
'police deployed around pound arresting rogue' is the wordplay.
I cannot really see how this works, but
'around' could be 'ca' (circa) and 'ca' is found in the answer.
'pound' could be 'l' (the pound sign is based on an L) and 'l' is found in the answer.
This explanation may well be incorrect...
'for' is the link.
Can you help me to learn more?
(Other definitions for peccadillo that I've seen before include "A little wrong" , "foible" , "Minor misdeed" , "minor faux pas" , "Minor offence" .)
