Takes broken slates without permission (6)

I believe the answer is:

steals

I'm a little stuck... Click here to teach me more about this clue!

'takes' is the definition.
(stealing is a kind of taking)

'broken slates without permission' is the wordplay.
'slates' can be anagrammed to 'STEALS'.
But, I'm not sure how the anagram is indicated.

Can you help me to learn more?

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

I've seen this clue in the Evening Standard.
