Federal officials say they will test all people detained at the Northwest detention center in Tacoma for COVID-19.

In a filing in federal court in Seattle, authorities said the testing at the immigration jail would be done Tuesday. The action comes after immigration advocates sued to try to free medically vulnerable detainees during the coronavirus outbreak.

The Northwest Immigrant Rights Project and the American Civil Liberties Union had argued there is no way to adequately protect people in custody from the coronavirus.

The Tacoma facility can house about 1,500 detainees, but as of May 12 had 645.
