Gunners turning up refreshed, ran in (8)
I believe the answer is:
arrested
'ran in' is the definition.
(run in can mean to arrest or apprehend)
'gunners turning up refreshed' is the wordplay.
'gunners' becomes 'ra' (Royal Artillery).
'turning up' says the letters should be written in reverse.
'refreshed' becomes 'rested' (similar in meaning).
'ra' backwards is 'ar'.
'ar'+'rested'='ARRESTED'
(Other definitions for arrested that I've seen before include "Stopped or slowed down progress" , "Detained by legal authority" , "stalled" , "Taken into police custody" , "on the way to . . . [PRISON] ?" .)
