Land some distance from police HQ (8,4)

Ross

I believe the answer is:

scotland yard

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

'police hq' is the definition.
(I've seen this before)

'land some distance' is the wordplay.
'land some' becomes 'scotland' (I can't justify this - if you can you should give a lot more credence to this answer).
'distance' becomes 'yard' (I've seen this before).
'scotland'+'yard'='SCOTLAND YARD'

'from' is the link.

Can you help me to learn more?

(Other definitions for scotland yard that I've seen before include "Former police HQ" , "(New) office for the Met" , "detectives" , "Metropolitan Police HQ" , "11 13 HQ" .)

I've seen this clue in The Daily Express.
