The police in Australia have raided two houses in Sydney, following suspected threats against a police station.

One house is the family home of Talal Alameddine, who was detained in October over the terror-linked killing of a police worker outside a police station.

Mr Alameddine is accused of supplying the gun which 15-year-old Farhad Jabar, used to murder police accountant Curtis Cheng.

Police said the searches were conducted under firearms legislation, but that no “items of interest” were found.

Mr Cheng was shot dead outside his office in Parramatta on October 2 in what the authorities said was a terror-related attack.
Iran-born Jabar was shot dead by police at the scene.

In the wake of the shooting, a number of people, including Mr Alameddine were arrested during police raids on several properties.

Mr Alameddine was released but later re-arrested and charged.

Australia has stepped up counter-terrorism efforts in recent months in the face of what officials said was a growing security threat from radical Islamists.
