“We believe that his actions were politically motivated and therefore linked to terrorism,” NSW Police Commissioner, Andrew Scipione told reporters in Sydney
The teenager, a naturalised Australian who arrived with his family from Iran, had walked to the police headquarters in Charles Street from his home in North Parramatta before opening fire on a civilian police employee, who has been identified as Curtis Cheng.
Mr Scipione said police had no information to suggest the gunman posed “this type of threat”.
“We’re a long way from establishing a full picture of this man, his exact motivations still remain a mystery to us,” he said “We are exploring every avenue with regard to why he did what he did.”
Prime Minister Malcolm Turnbull has described the terror-related shooting of a NSW police force member by a 15-year-old boy as a “cold-blooded murder”.
Mr Turnbull has urged Australians to go about their day normally despite the incident.
“This appears to have been an act of politically motivated violence so at this stage it appears to have been an act of terrorism. It is a shocking crime. It was a cold-blooded murder,” he told reporters in Melbourne.
