The party said police had sent letters as part of an investigation into a protest that blocked an Orange Order parade on Garvaghy Road.
Police in Northern Ireland contacted several Sinn Féin representatives and members as part of an investigation into the protest on Garvaghy Road, the party said. Police said people reasonably suspected of offences would receive letters inviting them for interviews.
The protest followed a court decision allowing the Orange Order to march along Garvaghy Road in Portadown. It was the first time in 28 years the disputed route through the predominantly Catholic area had been permitted. Protesters blocked the route, and the standoff continued for nearly two weeks.
Northern Ireland First Minister Michelle O’Neill and Sinn Féin leader Mary Lou McDonald took part in the protest. The Democratic Unionist Party (DUP) called for them and other lawmakers to be prosecuted, saying political office did not place anyone above the law. Sinn Féin said it stood with local residents.
Earlier attempts by the Orange Order to use the route had been accompanied by unrest. The route was banned in 1998 after the Good Friday Agreement. The latest dispute has developed into a political conflict and affected the work of Northern Ireland’s power-sharing government, led by Sinn Féin and the DUP.
