RIOT police locked down a central Sydney court on Thursday until an alleged gang member's trial was adjourned.
Responding to alleged threats to disrupt the matter before the Downing Centre courts, tactical and riot police, in full protective gear, arrived at the courts about 9am and stayed until midday.
Media reported five protective squad trucks, an armoured BearCat vehicle and PolAir helicopter patrolled the courts until the trial of two men was adjourned.
Police were quick to confirm to the media the response was not related to terrorism.
Police said the trial of a south-western Sydney criminal, alleged to be involved in an armed robbery in 2013 outside Broadway Shopping Centre, had been threatened with "disruptions".
The court precinct was not evacuated.
The two accused men, who cannot be named, remained in their cells on Thursday.
They face armed robbery, car-hijacking, aggravated break-and-enter and participating-in-a-criminal-group charges.
The Sydney Morning Herald reported senior police officers said one of the accused men was part of a group "more deadly and daring than the infamous Sydney crime group Brothers 4 Life".
The trial's start was adjourned until Monday morning - although will be briefly mentioned on Friday.
The accused will not be brought in until Monday.
