Terrorism accused's signs to loved ones

A man accused of supplying the gun involved in the fatal shooting of police accountant Curtis Cheng has used hand signals to communicate with loved ones in a NSW court.

Talal Alameddine allegedly supplied a .38 Smith & Wesson revolver to another man in October, before 15-year-old schoolboy Farhad Jabar used the weapon to kill Mr Cheng at NSW police headquarters.

The 23-year-old, who is also charged with knowingly being a member of a terrorist organisation, made what seemed to be hugging, telephone and baby-rocking gestures when he appeared in Parramatta Local Court via video link on Thursday.
