Muslim kills police worker in Australia

A teenage gunman who shot dead a NSW police worker outside the force's Sydney headquarters in an attack "linked to terrorism" has reportedly been identified as Farhad Khalil Mohammad Jabar.

Officially, police have only described the killer as a 15-year-old boy of Iraqi-Kurdish background and born in Iran, and say they won't confirm his identity until "all formalities" have been completed.

A day after the shocking attack which closed down parts of Parramatta, investigators are trying to work out what led to the teen, named in media reports as Jabar, to shoot Curtis Cheng as he left work at the State Crime Command on Friday afternoon.

Mr Cheng had worked for the police finance department for 17 years. Phone Post 3.0
