Police may investigate an alleged bombing attempt during an Indigenous rights protest in Perth, Western Australia, as a possible “terrorist” incident, following calls from Indigenous leaders and human rights groups for a more robust response from authorities. A search of the suspect’s home was conducted, where it was further alleged that a combination of chemicals and materials consistent with the manufacture of homemade explosives was found, Western Australia Police Force said in a statement. “Reports by rally organisers and witnesses raise serious questions about [Western Australia] Police’s response and communication with organisers, both before and after the attack,” the legal group said in a statement. Police alleged that the suspect removed the device from his bag and threw it from a walkway into a crowd of more than 2,000 people during the Invasion Day protest in Perth on Monday. Alerted by a member of the public, police took the man into custody and bomb response officers inspected the device, the Western Australia Police Force said in a statement.
