An academy in Staffordshire is believed to be the first school to have closed due to a confirmed coronavirus case since they reopened to pupils.
The JCB Academy in Rochester, Staffordshire, was one of the first schools to welcome pupils back at the end of August but told children to stay at home today.
In an email sent to parents late last night, the school said it was investigating a 'single case' of the virus but did not clarify whether a member of staff or a student tested positive.
The school has been closed 'as a precaution', with 700 of the 800 students being allowed to return to class next Monday.

Around 100 students have been asked to stay at home and self-isolate for the next 14 days.
The school has told parents not to be 'unduly concerned' by the outbreak but advised them to book a test for their child if they become symptomatic.
Principal Jenny McGuirk said the academy has taken advice from Public Health England and the Staffordshire Covid-19 Response Team.
She told the BBC: 'Through track and trace, academy staff have worked throughout the day to contact the families of students believed to have been in contact with the individual who has tested positive.

Self-isolating students will be able to access learning on Google Classroom for their lessons.
