Parramatta Shooting: Police HQ Gunman Was 15-Year-Old Boy

NSW Police have revealed that the lone gunman shot dead by officers after killing a police IT worker in Parramatta yesterday afternoon was a 15-year-old boy. 

Though the boy has not been named, police say that he is of Iraqi-Kurdish background, and that he arrived from Iran with his family as a child before becoming a naturalised Australian. 
Though the boy carried no identification, it is understood that his brother contacted police saying that he believed he knew who the gunman was. Police are currently trying to track down his family. 
Eyewitnesses say that the boy shouted religious slogans before approaching his target and shooting him in the back of the head, at 4.30pm yesterday afternoon. 
The victim of the horrific shooting has been named as Curtis Cheng, who had worked with the police force for 17 years, and was the father to a son and daughter.
The shooting took place outside the State Crime Command, which houses the state’s homicide, drug, Middle Eastern organised crime and gangs squads in its premises. 
Police Commissioner Andrew Scipione addressed the media this morning, saying that “we believe that his actions were politically motivated and therefore linked to terrorism … This is a very sobering time for us.”
Previously, a NSW Police source said that they had detected increased “chatter” for the past week, and that officers had been urged to wear firearms, even at their desks.
