A group of people with covered faces barged into the Center for the Collection of Insurance Debts in Athens slightly after 14:30 on Thursday, the Greek police said.
The members of the group entered the third and fourth floor of the building on 28 Pireos Avenue and broke glass partitions and computers. They left before the police arrived.
The antiestablishment group Rouvikonas assumed responsibility through a document uploaded on the internet. They explained that the cause of their attack was the case of a 62-year-old woman in Thessaloniki who was in danger of losing her small apartment over outstanding debts to EFKA, the state insurance fund.
