Flag protester Jamie Bryson was found in a converted attic – hours after taunting police over their failure to track him down, the High Court has heard.
Officers discovered him in a roofspace bedroom at the home of a pastor in Bangor.
The details emerged as the 23-year-old was remanded back into custody after a bail application was rejected.
Bryson, from Rosepark in Donaghadee, has been a high-profile spokesman for the Ulster People's Forum, set up in the wake of the Union flag protests.
Bryson is charged with six public order offences linked to the protests.
Family members, including his parents, were in the public gallery as Bryson appeared via video-link.
He was arrested by police last Thursday at the home of Pastor Mark Gordon – a day after going on the run following a raid at his home.
The court heard claims that Pastor Gordon tried to obstruct officers from reaching Bryson.
"Police indicated that when they attempted to apprehend the applicant at the home of an associate, the associate attempted to prevent police officers from entering the house, where they found Mr Bryson in the converted roofspace bedroom," a prosecution lawyer said.
She said Bryson had been active on social media sites before his arrest, referring to the PSNI as a "fascist force".
Objecting to bail, she raised concerns that Bryson could abscond, reoffend or re-engage in similar activity.
Defence lawyer Richard McConkey said Bryson had encouraged peaceful protests at all times, adding that prison has had a "significant impact" on him.
However, bail was rejected by Mr Justice McCloskey.
