Sinn Féin leader Mary Lou McDonald and Northern Ireland's First Minister Michelle O'Neill are to be interviewed by police in relation to their attendance at a counter-demonstration to the Drumcree Orange Order march.

The PSNI believed it was possible that dissident republicans may have used guns and petrol bombs to attack police officers if they attempted to clear protesters blocking an Orange Order parade along the Garvaghy Road, the High Court in Belfast has been told.
