Policeman seizing stolen loincloth (5)
I believe the answer is:
dhoti
'loincloth' is the definition.
(dhoti is a kind of loincloth)
'policeman seizing stolen' is the wordplay.
'policeman' becomes 'di' (I've seen this in other clues).
'seizing' indicates putting letters inside.
'stolen' becomes 'hot' (I've seen this before).
'di' going around 'hot' is 'DHOTI'.
(Other definitions for dhoti that I've seen before include "pants in Goa?" , "Indian attire" , "article of clothing" , "Lean over; end of loaf" , "Simple Indian garment" .)
