Harry barged about (6)
I believe the answer is:
badger
'harry' is the definition.
(both can mean to bother or harass)
'barged about' is the wordplay.
'about' is an anagram indicator.
'barged' with letters rearranged gives 'BADGER'.
(Other definitions for badger that I've seen before include "ride" , "A mammal; harry" , "hound perhaps?" , "Black and white burrowing mammal" , "Member of the weasel family" .)
