Remove trousers held inside baggage (5)
I believe the answer is:
debag
'remove trousers' is the definition.
(I've seen this before)
'held inside baggage' is the wordplay.
'held' indicates the answer is hidden within the clue.
'DEBAG' is hidden in the letters of 'inside baggage'.
(Other definitions for debag that I've seen before include "Strip of cords maybe" , "Remove (a person's) trousers" , "As a prank remove pants" , "Deprive of trousers" , "take trousers off" .)
