Eighty-one people have been reported to the PPS following an investigation into an unnotified parade.

Chief Inspector Jon Burrows statement:
"We promised there would be a robust and thorough investigation and we have been working very hard gathering evidence for prosecutions. This was a complex case and our commitment to it has been immense.
I am pleased to announce that we have concluded the investigation and have reported 81 people to the PPS for a variety of offences. The offences include participating in an unnotified parade as well offences relating to paramilitary style uniforms under Section 13 of the Terrorism Act 2000.
This was one of the largest investigations of its kind in this area and the number of people reported reflects the tenacious and professional investigation that followed the incident.
The PSNI in Armagh, Banbridge and Craigavon District want to work with communities so they can conduct events in a way that is peaceful and lawful, however we will thoroughly investigate instances where it is alleged the law has been broken”.
