I'm a little stuck... Click here to teach me more about this clue!

'up robbery' is the definition.
The definition suggests a singular noun which matches the answer.

'under protective cover evidently fraudulently set' is the wordplay.
I cannot really understand how this works, but
'set' could be 'rig' (synonyms) and 'rig' is found in the answer.
'cover' could be 'bandage' (cover for a wound) and 'bandage' is located in the remaining letters.
No letters remain.
This explanation may well be incorrect...
