Three young people were arrested after police were attacked in the Galliagh area of Derry on Saturday night.
Police said they received reports shortly after 10 p.m. that youths were blocking roads with burning debris in Glencaw Park and Leafair Gardens.
When officers arrived at the scene, they were attacked with stones, bricks and bottles.
Two of those arrested, boys aged 14 and 16, have been released pending reports to the Public Prosecution Service.
Another 16-year-old boy is still being questioned.
SDLP councillor Brian Tierney has appealed to young people in Galliagh to allow residents to live in peace.
He added: “Again, residents of Glencaw and Leafair had to put up with another night of what I would describe as serious anti-social behaviour with gangs of young people coming into this area intent on causing damage,” said Councillor Tierney.
“I am a resident here in Glencaw Park and I know that most of the young people here last night causing the trouble were not from this area. People are coming here to cause trouble and get the place a bad name for residents. That is unacceptable.
“Stones, bricks, bottles and other objects where thrown at police and residents cars with no care or thought for anyone’s property.
“The residents here just want to live in peace. We have put a lot of work into this area to try to reduce the levels of anti-social behaviour and we made great progress. The actions of a few last night won’t hold us back.
“We have plans in place for the months ahead but we need these young people to stop trying to run this area down and think of the effect their actions are having on the wider community” said Colr. Tierney.
