Dancing, one kidnapped by band of criminals? (8)

'dancing' is the definition.
(congaing is a kind of dancing)

'one kidnapped by band of criminals?' is the wordplay.
I cannot really understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
'band' could be 'gang' (I've seen this before) and 'gang' is present in the remaining letters.
'of' could be 'o' and 'o' is found within the answer.
This explanation may well be incorrect...
