Scandinavian police unit discovered crime when looking the other way (6)
I believe the answer is:
nordic
'scandinavian' is the definition.
(I know that scandinavian can be written as Nordic)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for nordic that I've seen before include "People of Northern Europe" , "Of tall, fair Germanic people" , "Type of cross-country ski racing" , "Finnish/Scandinavian" , "Relating to tall fair people of N Germany" .)
