Well-bred individual coming from Timor, Aceh or Serang? (9)

I believe the answer is:

racehorse

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

'well-bred individual' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.

'from timor aceh or serang?' is the wordplay.
'from' indicates a hidden word.
'RACEHORSE' is hidden within 'timor aceh or serang'.

'coming' is the link.

Can you help me to learn more?

(Other definitions for racehorse that I've seen before include "Steeplechaser, maybe" , "hope for better?" , "Animal" , "jumper?" , "Arab possibly" .)

I've seen this clue in The Times.
