In arrest I got criminal record (12)

Ross

I believe the answer is:

registration

'record' is the definition.

'in arrest i got criminal' is the wordplay.
'criminal' indicates anagramming the letters.
'in'+'arrest'+'i'+'got'='inarrestigot'
'inarrestigot' is an anagram of 'REGISTRATION'.

(Other definitions for registration that I've seen before include "Car ID" , "Formal enrolment" , "recording" , "Vehicle identifier" , "signing up" .)

I've seen this clue in The Telegraph.
