I'm a little stuck... Click here to teach me more about this clue!

'pickpocket might be' is the definition.
I can't tell whether this defines the answer.

'blonde felt' is the wordplay.
'blonde' becomes 'light' (I've seen this before).
'felt' becomes 'fingered' ('finger' can be a synonym of 'feel').
'light'+'fingered'='LIGHT-FINGERED'

'as' acts as a link.

Can you help me to learn more?

(Other definitions for light-fingered that I've seen before include "Having a propensity for stealing" , "Given to thieving" , "Liable to steal" , "Prone to steal" , "Inclined to steal" .)

I've seen this clue in The Telegraph.
