Surveillance operation (8)

Ross

I believe the answer is:

stakeout

(Other definitions for stakeout that I've seen before include "Police surveillance assignment" , "Secret surveillance by police" , "Informally, place under surveillance - using sharp stick?" , "Put under surveillance - like statue, OK?" , "watch closely" .)

I've seen this clue in The Times and The Guardian.
