Police have released a fresh tranche of images of people they are keen to speak to over illegal Union flag protests.
Detectives as part of Operation Dulcet have released a further 20 images of people they want to identify over 'obstructive sitting' in north and south Belfast as well as in Carrickfergus.
They also want to speak to those who may have been involved in 'unlawful procession' in east Belfast.
So far a total of 243 people have been arrested as part of the investigation into illegal Union flag protests earlier this year.
A total of 188 people have so far been charged.
Protests and sporadic violence flared after Belfast City Council voted to fly the flag on designated days only.
The vote in December triggered weeks of disruption right across Northern Ireland.
Detective Superintendent Sean Wright said he was confident that members of the public who could identify those pictured would come forward.
"We have released a number of images so far and we have had a very positive response from members of the public to date," he said.
"There are people out there who will know the identity of these 20 people who I am looking to speak to.
"It is vital that we all send out a message to those participating in un-notified processions and protests that such behaviour will not be tolerated.
"Those who break the law must face consequences for their actions. They will be dealt appropriately and proportionately through the criminal justice system."
The senior detective also appealed directly to those featured in the images to contact his team.
The team is investigating a range of offences which includes rioting and hijacking of cars along with attacks and death threats made against several politicians during weeks of unrest.
Police are appealing for anyone who may be able to identify those pictured to contact them on 028 90 901775.
