Trapped somewhere with a net, by the sound of it (6)
I believe the answer is:
caught
'trapped' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for caught that I've seen before include "Trapped or arrested" , "Came upon" , "Stopped and held a moving object" , "Way out in cricket?" , "report" .)
