Derry’s Shipquay Street has been reopened following a security alert.
Police at the scene say “nothing was found.”
Shops have now reopened and traffic is flowing through area again.
Foyle MLA Pat Ramsey said: “This is absolutely disgraceful and sickening. Traders here are angered beyond belief on what is the busiest day of the year for them. This is very very disruptive and it’s not a good day for the city.”
He added: “Those responsible for this today aren’t harming anyone except the people of this city. These actions achieve nothing except chaos and disruption for those caught up in them.”
Sinn Féin Foyle MLA Raymond McCartney said: “This is the last thing anyone wants to see happening in our city. Businesses in the city centre are finding it difficult enough to make a living and provide employment for local people without this disruption on one of the busiest shopping days before Christmas.
“Those behind these incidents need to get off the backs of the community .They are visionless and opponents of change who will not stop the people of Derry and beyond from moving forward to a more equal and peaceful society.”
