Police call out from the spinney (5)
I believe the answer is:
copse
'the spinney' is the definition.
(I've seen this before)
'police call out' is the wordplay.
'police' becomes 'cops' (cop can informally mean a police officer).
'call out' indicates a 'sounds like' (homophone) clue (I've seen 'called out' mean this).
'cops' is a homophone of 'COPSE'.
'from' is the link.
(Other definitions for copse that I've seen before include "Stand of trees" , "Cultivated woodland area" , "A little wood" , "Dense thicket of trees" , "Coppice" .)
