 A second weapon used in the 5 January attack was tied by the police to a 23 December 2008 attack on a police bus.That attack was reported to have been claimed by a group calling itself Popular Action (Λαϊκή Δράση, Laiki Drasi), as a response to the 2008 civil unrest in Greece.On March 10, 2010, two men were spotted breaking into a car (SEAT Ibiza) in Dafni, Attica at 4.40am and possibly resisted arrest by firing on the police officers.
