Detectives investigating the rioting in north Belfast on July 12 have released images of a number of people who they believe can help with their enquiries.
PSNI Chief Inspector Alan Little said he was hopeful that the public could assist police in identifying the nine people shown in the images.
To date 25 people have already been charged with various offences related to the trouble which broke out in the wake of a contested Orange Order parade through Ardoyne on the Twelfth.
Mr Little said: “From the start we have adopted a very proactive approach in relation to the investigation of public disorder both on the lead up to 12th July and following the scenes that were witnessed again this year.
“This approach has included taking every step possible to reduce the possibility of violence, including reviewing investigations from previous years.
“The investigation into the incidents at Ardoyne on 12th July has received strong support and we have had a very positive response from members of the public to date.
“I am now asking the local community to help identify these individuals whom we’d like to talk to in connection with our ongoing enquiries.”
Mr Little added: “The public disorder witnessed in the Ardoyne area on 12th July yet again wreaked havoc on local people and local communities.
“It is in everybody’s interest — as well as in the interest of justice — that those responsible are dealt with appropriately.
“There are people out there who will know the identity of the nine people who I am looking to speak to.
“I am confident that those people will come forward with that information.
“It is vital that we all send out a message to those involved in violent disorder that such behaviour will not be tolerated.”
