Since the beginning of the Syrian civil war in 2011, Syrian intelligence services have reportedly been systematically arresting, torturing and killing opposition activists. As a former member of the GID, Abdulhamid A. is suspected of having participated in crimes committed against the civilian population by the Syrian regime between 2011 and 2013.
On 12 February 2019, French authorities arrested Abdulhamid A. in the Paris region on suspicion of crimes against humanity. On the same day, German authorities arrested two other former GID officials, Anwar R. and Eyad A., in Germany. The arrests were coordinated in the context of a joint French-German investigative unit.
On 15 February 2019, Abdulhamid A. was indicted by the investigative judges of the specialized unit for the prosecution of genocide, crimes against humanity, war crimes and torture within the Paris Tribunal for complicity in crimes against humanity, and placed in pre-trial detention.
On 13 February 2020, Abdulhamid A. was released from pre-trial detention and placed under judicial supervision until the end of the investigation.
