Steal funds (6)
I believe the answer is:
I believe this is a double definition.
'steal' is the first definition.
(pocketing is a kind of stealing)
'funds' is the second definition.
(pocket is a kind of funds)
(Other definitions for pocket that I've seen before include "Take unlawfully" , "A ball-catching pouch on a snooker table" , "Pouch in garment" , "Take; isolated patch" , "Small isolated group" .)
