Bottles and stones hurled at police
Police were pelted with bottles, bricks and stones as they tried to deal with street disorder in Londonderry.
Trouble flared just after 10pm last night when officers responded to reports that youths were blocking roads in the Galliagh area with burning debris.
Three teenagers were arrested but two boys aged 14 and 16 have since been released pending reports to the Public Prosecution Service.
A third boy, aged 16, remains in police custody.
S DLP councillor Brian Tierney, who lives in the area, said residents' lives were being made miserable by the antics of the teenage gangs.
He said: "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.
"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."
A post on the PSNI's Foyle Facebook page appealed for parents to keep a closer watch over their children.
The PSNI said: "Most of these youths were also not local to Galliagh.
"Their behaviour could only be described as disgusting.
"Stones, bricks, bottles even bicycle saddles were thrown at police and residents' cars with no regards for anyone's safety or property.
"The residents just want to live in peace.
"We would like to ask parents out there, do you know where your child is? (We know where 3 are!)".
