Two Palestinian nationals, aged 40 and 42, and a 42-year-old Algerian alleged to be members of a theft and burglary ring that targeted the central Athens district of Acropolis, were detained by police on Friday.
The three men face a string of charges including running a criminal organization, theft and the illicit sale of goods.
According to investigators, the gang had been operating in the Acropolis area since 2012.
They are said to have targeted several stores and cars, selling on the loot.
The three men faced a prosecutor on Friday.
