Police in Derry have condemned what they described as "completely unacceptable behaviour" after a number of youths attacked officers in the Creevagh Heights area on Wednesday evening.
Police Service of Northern Ireland (PSNI) Superintendent Claire Hamilton said officers who were present as part of an ongoing policing operation came under attack from a group of youths who had gathered earlier and began making threats of violence towards police.
"Some of the youths were wearing masks, some were also armed with weapons, while some had tins of paint and fireworks," she said. "They subsequently proceeded to throw items, including stones and bottles, at officers, causing damage to two police vehicles."
Hamilton described the violence as "completely unacceptable behaviour – attacking officers while they're performing duties to protect the public – and we know it is not welcomed by the wider community."
A public safety operation remains in place, and police are engaging with local community representatives to appeal for calm.
