Police attending a security alert in Londonderry have been attacked with petrol bombs and fireworks.
No-one was injured during the disturbances in the Lecky Road area of Derry on Sunday.
Police and Army Technical Officers had attended the scene to examine a suspect device. The item later turned out to be what the PSNI described as an "elaborate hoax".
PSNI Chief Inspector Alan Hutton thanked residents who had been evacuated during the security alert for their patience.
He added: "However, I would strongly condemn the actions of a small group of people who threw missiles, including petrol bombs and fireworks, at officers whose only motivation is to protect the community they serve.
"This small minority of individuals showed a complete disregard for their area and the community who live there, by attacking police this afternoon.
"Their actions serve no purpose other than to cause harm to our community and lead to criminal convictions for young people.
"Thankfully no-one was injured and despite these incidents, police will continue to provide the dedicated service to the local community."
