Police evict a mob spoiling for a fight? (9)

I believe the answer is:

combative

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

'spoiling for a fight?' is the definition.
I can't tell whether this definition defines the answer.

'police evict a mob' is the wordplay.
'police' indicates anagramming the letters (police can mean to control or manage).
'evict'+'a'+'mob'='evictamob'
'evictamob' with letters rearranged gives 'COMBATIVE'.

Can you help me to learn more?

(Other definitions for combative that I've seen before include "Pugnacious" , "Eager to fight, aggressive" .)

I've seen this clue in The Guardian.
