Kid taken to court by police at last (5)
I believe the answer is:
suede
'kid' is the definition.
(two terms for types of leather)
'taken to court by police at last' is the wordplay.
'taken to court' becomes 'sued' ('sue' can be a synonym of 'take to court').
'by' says to put letters next to each other.
'at last' suggests the final letters.
The last letter of 'police' is 'e'.
'sued'+'e'='SUEDE'
(Other definitions for suede that I've seen before include "Type of leather" , "Leather with flesh side rubbed to velvety nap" , "Soft leather with one side napped" , "Undressed leather" , "Kid possibly" .)
