Asian bloke arrested by call to attention (5)
I believe the answer is:
omani
'asian' is the definition.
(Oman is an Asian country)
'bloke arrested by call to attention' is the wordplay.
I cannot quite see how this works, but
'bloke' could be 'man' (informal term for a man) and 'man' is located in the answer.
'call' could be 'oi' (call used to attract attention) and 'oi' is found in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for omani that I've seen before include "From an Arabian country, capital Muscat" , "Citizen of a country, capital Muscat" , "Eg, a native of Muscat" , "one from the Middle East" , "Native of one Arabian sultanate" .)
