Robber gang taking computer technology (6)
I believe the answer is:
bandit
'robber' is the definition.
(thesaurus)
'gang taking computer technology' is the wordplay.
'gang' becomes 'band' (I've seen this before).
'taking' says to put letters next to each other.
'computer technology' becomes 'it' (I've seen this in other clues).
'band'+'it'='BANDIT'
(Other definitions for bandit that I've seen before include "Armed robber in the Wild West" , "Marauder" , "Member of a robber gang" , "Dan bit the robber badly" , "Highwayman" .)
