Fracking stones securing capital (8)

I believe the answer is:

kingston

'capital' is the definition.
(capital of Jamaica)

'fracking stones securing' is the wordplay.
'securing' indicates the answer is hidden within the clue.
'KINGSTON' is hidden within 'fracking stones'.

(Other definitions for kingston that I've seen before include "Capital of Jamaica" , "Jamaican capital" , "island capital" , "Royal borough on river Thames" .)

I've seen this clue in The Telegraph.
