Worry gangster has got in (5)

I believe the answer is:

angst

'worry' is the definition.
(I've seen this before)

'gangster has got in' is the wordplay.
'has got in' indicates a hidden word.
'ANGST' can be found hidden inside 'gangster'.

(Other definitions for angst that I've seen before include "Terrible butterflies" , "Profound feeling of anxiety or dread" , "Great anxiety" , "feeling worried?" , "Philosophical unease" .)

I've seen this clue in The Times.
