Small English bloke twice turns up to identify culprits (4,5)

I believe the answer is:

name names

'identify culprits' is the definition.
(to name names is to identify wrongdoers)

I don't understand the remainder of the clue.

(Other definitions for name names that I've seen before include "Accuse specific people" , "identify those involved" , "say who they are" .)

I've seen this clue in The Independent.
