Loyalists are expected to hold a number of unnotified parades across Northern Ireland this weekend in an act of "civil disobedience" intended to stretch police resources.
A parade was held in Portadown earlier this week with men in balaclavas seen accompanying a loyalist band. A similar parade was also held in Markethill in Co Armagh.
Neither parade was notified to the Parades Commission, the body tasked with determining if individual parades, marches and processions are legal.
Similar tactics are now expected to spring up across Northern Ireland, with the first parades planned for this weekend.
To date loyalist band parades have been planned for parts of Mid Ulster, North Down and Antrim.
The Belfast Telegraph understands that the organisation of the gatherings is to take place in private groups, to stop the action being used by "concerned agitators" suspected of trying to whip up tensions at volatile interface areas.
The PSNI are believed to be tracing the IP addresses of a number of Facebook pages that were set up just weeks before the unrest last weekend that were promoting gatherings.
Once such protest, advertised on the social networking site, attracted hundreds of young people resulting in violent clashes with police in the Sandy Row area of Belfast.
A senior loyalist source said unnotified parades across various locations in Northern Ireland are "planned for the weekend" with the tactic expected to last well into the summer marching season.
The Mid Ulster loyalist added that they were "concerned agitators are using social media to try to draw young people into violence rather than peaceful protests, so plans for the pop-up protest parades are being kept largely away from social media".
Police are aware that there are plans for unnotified parades, but not the details of when and where, which is expected to stretch resources over the weekend.
On Wednesday Orange Order Grand Secretary, the Rev Mervyn Gibson, posted on Twitter that bandsmen had been approached by police to enquire about any future plans.
One loyalist claimed to have been visited by police and asked about his band's position on the current unrest. It is not known how many other bands were also approached by the PSNI.
A police spokesperson said: "Police engage with the communities they serve on an ongoing basis on a range of issues to help keep people safe."
Loyalist Jamie Bryson said there was an appetite among many loyalist groups to withdraw support for the Parades Commission and engage in "civil disobedience throughout the summer in relation to parading".
"The Parades Commission is just another element of the unjust system inflicted upon our community for the last two decades. It makes sense that some may conclude that the time is right to peacefully bring down the Parades Commission, and the way I suppose they may seek to do that is by urging the Orange Order and all bands to refuse to cooperate with it," he said.
"The parading regulation system only works with consent of those being regulated, if that consent were to be withdrawn then the system would be unworkable.
"The DUP and UUP have not gone far enough regarding policing."
Mr Bryson said that "for many the PSNI are to loyalists what the RUC were to nationalists". Yesterday UUP leader Steve Aiken said "Northern Ireland and its people need a police service".
His comments were echoed by the party's Upper Bann MLA Doug Beattie.
Mr Beattie said he was aware of plans for band parades in his own constituency at the weekend.
"We are in the middle of a Covid pandemic and people should adhere to the rules and regulations, we know mass gatherings are still frowned upon and it's important I say that," he said.
"But there is another side to this as well, I wish they would engage with at the very least their local community police and that existing apparatus, they are on their side and they want to make sure if parades do go ahead they are safe.
"There are safety issues around speaking to police, because the last thing anyone wants is a parade taking place no one knows about and a car ploughing into the back of it. But whatever they do, if there's a commitment to remain peaceful, then peaceful parades are better than what we have seen."
