Robbers grab URLs deviously (8)
I believe the answer is:
burglars
'robbers' is the definition.
The definition and answer can be both people as well as being plural nouns.
Perhaps you can see an association between them that I don't see?
'grab urls deviously' is the wordplay.
'deviously' indicates an anagram (I've seen this in other clues).
'grab'+'urls'='graburls'
'graburls' anagrammed gives 'BURGLARS'.
Can you help me to learn more?
(Other definitions for burglars that I've seen before include "Thieves, robbers" , "Thieves who break into buildings" , "Intrusive thieves" , "They break in to steal" .)
