A foreigner, frightened-looking, seen rushing around (8)

I believe the answer is:

nepalese

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

'a foreigner' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for nepalese that I've seen before include "Gurkhas" , "High-up person perhaps" , "From Kathmandu?" , "High Country people" , "foreign" .)

I've seen this clue in the Evening Standard.
