Trapped, captured (6)
I believe the answer is:
caught
I believe this clue is a double definition.
'trapped' is the first definition.
(I've seen this before)
'captured' is the second definition.
('catch' can be a synonym of 'capture')
(Other definitions for caught that I've seen before include "Ensnared" , "Trapped or captured" , "Way out in cricket?" , "Stopped and held a moving object" , "Apprehended" .)
