Four men, including one from Dungannon, were greeted with cheers, chanting and clapping when they appeared in court to face charges of planning acts of violence.
The men were been remanded in custody charged with dissident republican terrorist offences after police seized an improvised explosive device.
Luke O’Neill, 22, from Silverwood Green in Lurgan, Co Armagh, is accused of attempting to murder police officers between August 30 and September 2 this year as well as possession of explosives with intent to endanger life.
Damien Duffy, 46, from Westclare Court in Dungannon, Co Tyrone, Ciaran Magee, 24, from Lake Street in Lurgan, Co Armagh, and Shea Reynolds, 22, from Kilwilke Road, also in Lurgan, are charged with preparation of terrorist acts, namely targeting a former member of the security forces.
All four appeared in the dock at Craigavon Magistrates Court wearing tracksuits.
They refused to stand before District Judge Peter King as details of the charges were put to them.
The men were arrested last week after a large-scale security operation during which police recovered a fully-prepared, explosively-formed projectile that was ready for deployment.
A detective sergeant from the PSNI said he believed he could connect all four men to the charges.
The court was told that a camera had been placed in a house overlooking the home of a former member of the security forces.
It was alleged that Reynolds’ fingerprint was found on the camera and that his picture was also on an SD card (a type of electronic storage device).
However, police do not know the whereabouts of the camera now, the court heard.
Outlining objections to bail for Reynolds – the only defendant to make an application – the officer said there was a risk of interfering with the ongoing investigation and a likelihood of interfering with witnesses.
He also said the defendant may abscond in order to avoid a long jail term, if convicted.
Defence barrister Peter Corrigan challenged the objections, and said his client was a man of good character who had never before been arrested or interviewed by police.
He said the 22-year-old had a five-year-old child and his partner is to give birth soon.
He had a good job and strong ties to the local community, the lawyer said.
There were also issues about the strength of the evidence, he added.
Mr Corrigan said declining bail would be like “driving a coach and horses through the presumption of innocence”.
However, District Judge King told the court he was concerned about the risk of interfering with witnesses and the ongoing investigation and remanded Reynolds into custody.
A bail application for Magee is expected to be made next week, the court was told.
No bail applications were made for O’Neill or Duffy – who is a brother of prominent republican Colin Duffy.
There was standing room only in the small courtroom, which was packed with people including friends of the accused.
Some of those present wept as they were led into the dock in handcuffs.
Ahead of the hearing, District Judge King warned supporters he would clear the court if there was disruption.
At one point there was loud laughter as it emerged the prosecution had been given the wrong record for Reynolds, whose record is clear.
As they were led to the dock, a number of the defendants gave the thumbs-up to supporters.
Throughout the hearing they spoke to and joked with each other and gestured to others in the public gallery.
There was also a significant police presence, with riot squad officers both inside and outside the court.
There was loud applause, cheering and chants of “Keep ‘er lit” as the men were led out of the dock. The cheers continued as they were driven away in a police van.
The case has been adjourned, with Magee next due to appear on October 7, and Reynolds, O’Neill and Duffy to appear via video-link on October 21.
