Arrested, having committed a theft (7)
I believe the answer is:
pinched
This clue might be a double definition.
'arrested' is the first definition.
Both the answer and definition are adjectives. Maybe there's a link between them I don't understand?
'committed a theft' is the second definition.
The definition and answer can be both to do with ownership as well as being past participle verbs.
Maybe there's an association between them I don't understand?
'having' is the link.
Can you help me to learn more?
(Another definition for pinched that I've seen is " Haggard".)
