A group of 10 to 15 masked perpetrators on Wednesday afternoon targeted a campaign event by an Athens municipal candidate that was attended by former prime minister Antonis Samaras and ex-public order minister Vassilis Kikilias, among others.
Three vehicles were damages, along with other instances of vandalism at a hotel off Syngrou Avenue, a major thoroughfare that connects the city's center with the seafront.
The group of "antifa-like" perpetrators used a pedestrian bridge over the avenue to reach the venue.
A bevy of incidents and attacks have been attributed to so-called anti-state and self-styled anarchists over the past week, ostensibly in demand of another prison furlough for notorious "November 17" arch-assassin and terrorist Dimitris Koufodinas.
