Australian Federal Police arrested Mohammad Emad uddin Ahmadzai, 30, on Saturday evening at Melbourne Airport as he was preparing to board an Etihad Airlines flight to Kabul, Afghanistan. The arrest is linked to an alleged extremist group chat where violent material was shared.

Ahmadzai's arrest is the sixth in connection to the group chat. Four men were charged in May, and another was charged upon returning to Australia from Malaysia. All their cases are currently before the courts.

During a raid of a property in Roxburgh Park, north Melbourne, on May 7, police seized multiple devices from Ahmadzai and his brother, including two iPhones, an iPad, and an alleged improvised weapon. Forensic examination of the devices reportedly uncovered extremist material depicting extreme violence, including shootings, hostage executions, beheadings, and throat slashings. The devices also allegedly contained images of deceased children in Gaza and ISIS flags and logos.

Police allege the devices belonged to Ahmadzai and that he participated in a group chat used to share extremist content. During a recorded interview, Ahmadzai stated he was traveling with his family to visit his sick father in Kabul via Abu Dhabi.

Authorities also searched a suitcase belonging to Ahmadzai, seizing an Apple computer, children's paracetamol, and a small vial of clear liquid.

Ahmadzai has been charged with one count of possessing violent extremist material and contravening a requirement under the Crimes Act. The matter is scheduled to return to Melbourne Magistrates' Court on Tuesday.

AFP Commander Counter Terrorism South Paula Hudson stated that Australian police are committed to combating online extremism. She added that the creation and sharing of violent extremist material can lead to radicalization, particularly among youth, and that the AFP considers such offenses very seriously.
