Reference facsimile fooling Yard initially, ensnaring corrupt police (4,4)

'reference facsimile' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'fooling yard initially ensnaring corrupt police' is the wordplay.
'initially' indicates taking the first letters.
'ensnaring' is an insertion indicator.
'corrupt' indicates anagramming the letters (a corrupted spelling of the word).
The initial letters of 'fooling yard' is 'fy'.
'police' anagrammed gives 'ilecop'.
'fy' enclosing 'ilecop' is 'FILE COPY'.

Can you help me to learn more?
