General Motors has confirmed one of its employees at its Tech Center campus in Warren, Michigan has tested positive for COVID-19. The news has caused GM to close its engineering building on the sprawling complex.

“We just learned yesterday that an employee who works at the Cole Engineering Center in Warren has tested positive for the virus,” said Jim Cain, GM spokesman told the Detroit Free Press.

Upon hearing the diagnoses Monday GM shut off the card swipes that grant employees access to the building. The automaker says it is currently cleaning the building and doing everything “medically and scientifically called for” to make the building safe for employees. In the meantime GM has asked employees at this portion of the Tech Center to work remotely if they can.

GM says any employees who came in contact with the employee who has tested positive will have to quarantine for 14 days. The company is in contact with employees who may be at risk of exposure.

Expect further updates from GM as this story develops.
