Plagiarises Astle's cryptic (6)

I believe the answer is:

steals

'plagiarises' is the definition.
(I've seen this in another clue)

'astle's cryptic' is the wordplay.
'cryptic' indicates anagramming the letters (a cryptic or obscure order of the letters).
'astles' anagrammed gives 'STEALS'.

(Other definitions for steals that I've seen before include "Takes without owner's consent" , "Robs" , "Purloins" , "Takes property without right or permission" , "Pilfers" .)

I've seen this clue in the Sydney Morning Herald.
