[4][11] Marić was arrested at the Fremantle home of Stjepan Brbić, a wartime Ustaša member who had replaced Srećko Rover as the Croatian National Resistance (HNO) leader in Australia.
Brbić had previously established a Vjekoslav Luburić Society in Sydney and was believed to be the main organiser for the George Street bombings.
