During the pre-dawn hours of 7 July 2022, an explosive device was detonated at a government tax office on Plataion Street in Maroussi, a northern Athens suburb. According to local officials, the blast destroyed several windows and damaged office infrastructure; however, there were no injuries due to the absence of employees inside the building at the time of the explosion. An anarchist group that was previously unknown to police has claimed responsibility for the blast and offered proof of its involvement by detailing the devices used in the explosion. The counterterrorism unit of the local police force has begun an investigation into the attack.
