Criminal not masked? I’ve no idea (4,3,2)

Ross

I believe the answer is:

dont ask me

'i've no idea' is the definition.

'criminal not masked?' is the wordplay.
'criminal' is an anagram indicator.
'not'+'masked'='notmasked'
'notmasked' with letters rearranged gives 'DONT ASK ME'.

I've seen this clue in The Times.
