Local actor twisted police case, wiped out by steroid type (8)
I believe the answer is:
anabolic
'local' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for anabolic that I've seen before include "Encouraging muscle growth" , "Such steroids enhance sporting performance" , "Promoting the increase of body tissue, as do some steroids" , "-- Steroid" .)
