Turns up, so alike central figures the guards mention in a drugs bust (5)
I believe the answer is:
kilos
'figures the guards mention in a drugs bust' is the definition.
I can't judge whether this definition defines the answer.
'turns up so alike central' is the wordplay.
'turns up' shows that the letters should be reversed in order.
'central' means to look at the middle letters.
The middle of 'alike' is 'lik'.
'so'+'lik'='solik'
'solik' backwards is 'KILOS'.
Can you help me to learn more?
(Other definitions for kilos that I've seen before include "Units of weight in metric system" , "Metric weights" , "Units of weight of 1000 grams" , "Units of mass" .)
