Steals nothing reportedly (5)
I believe the answer is:
nicks
'steals' is the definition.
(I've seen this before)
'nothing reportedly' is the wordplay.
'nothing' becomes 'nix' (nix can mean nothing).
'reportedly' shows a homophone (sound like).
'nix' sounds like 'NICKS'.
(Other definitions for nicks that I've seen before include "Notches - arrests" , "Small cuts" , "chips" , "Arrests (slang)" , "Pinches or makes a small cut" .)
