Peter has fabricated a criminal record (3,5)
I believe the answer is:
rap sheet
'a criminal record' is the definition.
(a rap sheet is a police record)
'peter has fabricated' is the wordplay.
'fabricated' indicates anagramming the letters.
'peter'+'has'='peterhas'
'peterhas' anagrammed gives 'RAP SHEET'.
(Other definitions for rap sheet that I've seen before include "Criminal record, colloquially" , "Where to find previous" , "record of arrests" , "'Written record of charges (3,5)'" .)
