Five men have been released on bail following dawn raids after protests at Grey's Monument ended in violence.
Northumbria Police arrested 14 people on Saturday after a group labelling itself the 'Defenders of Newcastle' became involved in violent scenes around Grey's Monument with Black Lives Matter protesters.
And on Thursday morning five more were taken into custody following raids around the region.
The men, aged 39, 42, 44, 51 and 55, were all arrested on suspicion of violent disorder but the force confirmed they have all now been released under investigation.
The lead officer has warned that more arrests are likely and CCTV images of five men who police want to speak to were released.
Assistant Chief Constable Scott Hall said: “The violent disorder we saw on Saturday was completely unacceptable and will not be tolerated.
“We have made it abundantly clear that anyone found to have been involved will be brought to justice.
“Since the weekend, a dedicated team have been working to identify those believed to have been involved, which has today resulted in a number of suspects being arrested.
“However, this activity is still very much ongoing – and we expect to be making more arrests in the very near future.
“My message to anyone who was involved in the disorder is a simple one – come forward and hand yourself in to police.”
As part of the ongoing investigation – named Operation Travis – officers are trawling through hours of CCTV and bodyworn camera footage.
They are now also appealing for anyone who may have images or footage from the day to get in touch.
Anyone who has footage or images, is urged to share this through the UK Policing Major Incident Public Portal reporting site – visit www.mipp.police.uk and click on the Northumbria Police badge.
