Fifteen officers were injured in rioting last night in Sandy Row in South Belfast.
Eight young people were arrested including two young boys, aged 13 and 14.
Three other teenagers aged 17, 18 and 19 were arrested along with a 19-year-old female.
Two others aged 21 and 25 were also arrested.
Belfast District Commander Chief Superintendent Simon Walls said the majority of those involved in the disorder last night were young people.
A small protest quickly developed into an attack on police officers.
The officers were injured after being subjected to a sustained attack by rioters who threw a number of objects at police, including heavy masonry, metal rods, fireworks and manhole covers. Their injuries include burns, head and leg injuries.
Chief Superintendent Simon Walls said by engaging in this type of behaviour the young people are not only risking their safety, they are also risking their futures.
He added: “I understand there are significant tensions and unease in some communities. My job is to keep people safe and I would ask that anyone who has any influence in communities – whether parents, guardians, community or elected representatives – please, use that influence to ensure young people are kept safe and away from harm.
“Local communities deserve to live in safe and peaceful areas, free from rioting and violence.”
