Five teenagers have been arrested after fresh trouble erupted in Derry’s Bogside and Galliagh areas overnight.
In a repeat of events over previous evenings, police received reports of young people setting pallets and rubbish on fire in the Lecky Road and Westland Street areas.
A PSNI spokesman said: “Police responded immediately and a number of petrol bombs and missiles were thrown at them.
Four young males, one aged 14 and three aged 16, were arrested in the Westland Street area on suspicion of riotous behaviour.
“They were subsequently released on police bail pending further enquiries.”
In a separate incident, a 16-year-old male was arrested in the Collon Lane area on suspicion of disorderly behaviour.
He has been released pending a report to the Public Prosecution Service.
Police have confirmed that a crate of petrol bombs and number of other items were seized by police.
Chief Inspector Andy Lemon said: “The prompt actions of our officers prevented a reoccurrence of the disorder we saw the previous night.
“It is concerning to see teenagers, some as young as 14, getting caught up in this violence and I appeal to parents to make it their business to know where their children are and what they are doing.
“Young people need to listen to our message - you run the very real risk of being arrested and getting a criminal record which could affect your life for a very long time.”
He added: “I appeal to anyone with any information about those involved in the disorder last night to contact police at Strand Road on the non-emergency number 101.”
