Nicola Sturgeon said that the government would be “paying close attention” to 15 new coronavirus cases in the Greater Glasgow area, as she announced the first local lockdown in Scotland.

The First Minister revealed the re-imposing of restrictions after 56 positive cases were linked to an outbreak related to pubs in Aberdeen and surrounding areas.

Pubs, restaurants and cafes in the city were ordered to close and people told not to visit other households for the next seven days.

People outside the city are told not to travel to Aberdeen and those living there not to travel more than five miles unless for work or absolutely necessary.

Ms Sturgeon said that everyone should take the re-imposing of lockdown as a warning what can happen if we ignore the precautions and the rules that are still in place.

She said: This virus hasn’t gone away. If you doubted that then today we have evidence of how true that is.

“It is still out there – and it is still highly infectious and it is still highly dangerous.

“The outbreak in Aberdeen is a sharp reminder of that. It shows what can happen, if we let our guard drop. And it should serve as a warning to all of us.

“Just because many of the restrictions have been eased across the country, doesn’t mean we can simply go back to normal. We are still in a real daily battle with this virus. And so, we must all continue to exercise extreme caution.”

The outbreak was linked to a list of 20 bars, restaurants and golf clubs in the north east.

Ms Sturgeon said again around half of the new cases were in people in their 20s and 30s.

She said it was thought, but not confirmed, that many had been going from pub to pub.

The latest statistics showed 64 new cases in the last 24 hours across Scotland.

The First Minister said it was: “The highest daily number we’ve reported for quite some time.

Fifteen of the new cases were in the Greater Glasgow Health Board area.

Ms Sturgeon added: “We will be paying very close attention to those and any possible patterns as well.”

There were 267 patients in hospital who have been confirmed with the virus, three fewer than the day before.

Three people were in intensive care with confirmed COVID-19.

Ms Sturgeon added: “Yesterday’s reported figure of four was later revised down to three, so today’s number is actually the same as yesterday.”

Licensed trade bosses warned everyone must play their part in keeping the virus under control.

Colin Wilkinson, Scottish Licensed Trade Association managing director, said: “The SLTA acknowledges the fragile situation we are all operating in and we cannot emphasise enough the need for everyone to adhere to the guidance, businesses, staff and customers alike.

“All premises must also operate the Test and Protect scheme which is so important in stopping the spread of the virus.”

Earlier this week the Glasgow Times reported how some pubs were not collecting customers details for the test and protect scheme amid calls for it to be mandatory.
