Starting from December 2012, Greek Police initiated extensive raids in a number of squats in Athens, arresting and charging with offences all illegal occupants (mostly anarchists). Squats including Villa Amalia were evicted. A march in support of the 92 arrestees drew between 3,000 and 8,000 people. After Villa Amalia, Villa Skaramanga and then Villa Lela Karagianni were evicted. Lela Karagianni had been squatted since 1998 and was later reoccupied.
