THE PSNI say that the security alert under the flyover at Lecky Road in the Bogside has now ended.
Following an examination of a suspect device, ATO declared it a hoax device.
Fifteen families evacuated from their homes earlier have now been allowed to return.
During the alert police came under attack from misguided youths throwing petrol bombs and fireworks at police.
Chief Inspector Alan Hutton said: “The security alert in the Lecky Road area of Derry/Londonderry has ended and those evacuated from their homes have been allowed to return.
“The suspect device has been declared a hoax by ammunition technical officers (ATO).
“I would like to thank residents in the area and members of the public for their continued patience while we worked to keep everyone safe.
“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.”
