Crossword Genius

Prison officer in need of a driver? (5)

Ross

I believe the answer is:

screw

This clue is a double definition.

'prison officer' is the first definition.
(slang term)

'a driver?' is the second definition.
(thesaurus)

'in need of' acts as a link.

(Other definitions for screw that I've seen before include "Tapered fastener with a slotted head" , "Apply backspin (snooker)" , "Archimedes' invention" , "Hack" , "something with thread" .)

I've seen this clue in the Evening Standard.
