Arrest OAP cavorting with this puffin (3-6)

I believe the answer is:

sea-parrot

'this puffin' is the definition.
(I've seen this in another clue)

'arrest oap cavorting' is the wordplay.
'cavorting' indicates anagramming the letters.
'arrest'+'oap'='arrestoap'
'arrestoap' with letters rearranged gives 'SEA-PARROT'.

'with' is the link.

I've seen this clue in The Irish Times.
