Information from an intelligence officer (3)

I believe the answer is:

gen

'information' is the definition.
(gen is a kind of information)

'from an intelligence officer' is the wordplay.
'from' says the answer is hidden in the clue.
'GEN' is hidden within 'intelligence officer'.

(Other definitions for gen that I've seen before include "Informal information" , "'Information, colloquially (3)'" , "Info" , "Knowledge" , "Information yielded" .)

I've seen this clue in the Evening Standard.
