Coronavirus updates: State reports over 49,000 new cases, 468 new deaths

Scottish authorities arrested and charged Parliament Member Margaret Ferrier following an investigation that found she broke COVID-19 rules in September, according to the Police Service of Scotland.

Ferrier traveled between Glasgow and London twice while she had COVID-19 symptoms, and in the second instance was aware she had tested positive for the virus.

"We can confirm that officers today arrested and charged a 60-year-old woman in connection with alleged culpable and reckless conduct," a Police Scotland spokesperson said in a statement Monday. "This follows a thorough investigation by Police Scotland into an alleged breach of coronavirus regulations between 26 and 29 September 2020."

Ferrier, a member of the Scottish National Party, posted an apology on Twitter in October:

"On Monday evening I received a positive test results for COVID-19," she tweeted. "I travelled home by train on Tuesday morning without seeking advice. This was also wrong and I am sorry. I have been self-isolating at home ever since."

Ferrier was suspended by the Scottish National Party after information about her infraction came to light, but has so far resisted calls for her resignation.

"I feel good," Lindsay told reporters Monday. "I don't feel any way different before I got it. I hope the vaccine is available to everyone as it was for me," she added.

The United Kingdom is expected to announce tight lockdown restrictions Monday, following a recommendation from the nation's chief medical officers to move to the highest COVID-19 alert level -- alert level 5 -- across the country. The U.K. has been at alert level 4 since September.

"Cases are rising almost everywhere, in much of the country driven by the new more transmissible variant," the chief medical officers said in a statement Monday. "We are not confident that the NHS can handle a further sustained rise in cases and without further action there is a material risk of the NHS in several areas being overwhelmed over the next 21 days."

British Prime Minister Boris Johnson is set to announce additional measure to control the virus during a televised address Monday evening.
