Petrol bombs and masonry have been thrown at police during a third night of disorder in the Tullyally area of Derry/Londonderry.
A number of youths are believed to have been involved in the incident which began at around 8pm last night.
Police say fires were also being lit and one officer at the scene was struck by masonry but was able to continue with their duties.
A 17-year-old boy was arrested on suspicion of riotous behaviour but has since been released on bail pending further enquiries.
Officers also seized 15 petrol bombs from the area.
Chief Inspector Bob Blemmings said: “Young people engaging in this type of criminal behaviour are risking, not only their own safety, but they also face the possibility of a criminal conviction.
"This is the third consecutive night we have witnessed these reckless attacks which are harming the local community.
"We would appeal to parents and guardians to make sure their children are not getting drawn in to activity that will bring them to the attention of police.
“We will continue to work alongside local representatives and partner agencies to ensure local residents can live in peace.”
