Police prevented the Orange Order from making a parade down Garvaghy Road in Portadown in the early hours of Monday. A line of police Land Rovers stood in the way as a group of men attempted to march from Drumcree Church.
The Orange Order had been unable to complete the permitted parade on Sunday morning due to protesters gathering on the mainly-nationalist Garvaghy Road. The stand-off continued throughout Sunday, with Orangemen waiting at the church for police clearance.
Sinn Féin First Minister Michelle O'Neill joined the protest, prompting Democratic Unionist Party (DUP) leader Gavin Robinson to accuse her of acting unlawfully. Northern Ireland Secretary Sir Chris Bryant called for "compromise" amidst the dispute.
The Parades Commission had decided on Friday that the march could go ahead with restrictions, following 28 years of unsuccessful applications. This decision was challenged in Belfast courts on Saturday but was ultimately given the go-ahead hours before it was due to take place.
Police Service of Northern Ireland Chief Constable Jon Boutcher stated that officers had been gathering evidence from the outset of the events. Two local schools announced they would close on Monday due to the ongoing situation, citing safety concerns.
