Sydney terror plot: man arrested

Another Sydney man has been charged over an alleged terror plot targeting Australian police and military locations.

Farhad Said, 24, was arrested by counter-terrorism officers outside his Chapel Road, Bankstown home on Thursday morning as part of investigations into alleged plans to attack the Australian Federal Police Sydney headquarters and the Garden Island Naval Base.

He has been charged with conspiring to do acts in preparation for a terrorist act.

Said did not face Sydney's Central Local Court and his lawyer, Muhammad Tehseldar, requested he not be shown on the court's audio visual system.

He made no application for bail and it was formally refused.

Said is expected to remain behind bars until June 8 when a number of co-accused are also expected to return before court on the same charge.

It relates to the alleged preparation of handwritten documents seized by the AFP and NSW Police during Operation Appleby raids across Sydney in December 2014.

Court documents name six co-accused, including Sulayman Khalid, Ibrahim Ghazzawy and Maywand Osman, who are also in custody.

Another co-accused, who cannot be named for legal reasons, was aged just 14 at the time of the alleged plot and is on bail.

The AFP says Said's arrest is based on that information and the public were at no immediate risk on Thursday.

Police have until June 2 to finalise and serve their brief of evidence.
