Police are investigating further disorder in Belfast last night.
The disorder occurred in various parts of the city including Duncairn Gardens -Tigers Bay area, and North Queen Street.
During the disorder, which started shortly after 5pm, petrol bombs and masonry, including roof tiles, were thrown at police. There was an attempt to hijack vehicles on Limestone Road and, on North Queen Street, a car was hijacked and set on fire and pushed towards police lines.
Three male teenagers, all aged 14 years old, were arrested during the disorder and they have all been released pending further enquiries.
As a result of the disorder on North Queen Street, 14 officers were injured bringing the total number of officers injured during recent disorder to 88.
Chief Inspector Darren Fox said: "These were disgraceful scenes, which lasted until approximately 1am, that unfolded on the streets of our city last night. This was reckless and dangerous criminal behaviour which resulted in a number of our officers sustaining injury. Thankfully, most of these injuries are not serious. However, a male officer was knocked unconscious and required hospital treatment. As you can imagine, none of our officers go out expecting to be attacked in this way.
"Again, we reiterate our message that this shameful and senseless behaviour is achieving nothing other than wrecking local communities. Residents in these areas, or indeed anywhere, do not want or deserve to experience the fear many of them will have felt in recent nights.
“I am appealing to all those with influence to help bring this violence to an end and, to parents, guardians and community leaders, we ask that you use your influence to ensure we do not see a repeat of such disorder.
“The community can be reassured we will continue to work to keep people safe, and an investigation is underway and evidence gathered will now be reviewed and those identified will face the full rigour of the law.”
