Three inmates at the Cumberland County Jail in Portland have become infected with the coronavirus as part of a new outbreak of the disease, according to state health officials. 

One of those cases was already announced last month, when a person arrested by Westbrook police on June 27 for criminal threatening and disorderly conduct tested positive. 

At the time, the Cumberland County Sheriff’s Office said the person was exposed to the virus outside the jail and moved to a negative pressure cell, with an expected release on bail a few days later. All staff and inmates were required to wear face masks until further notice, the sheriff’s office said at the time. 

The sheriff’s office did not immediately respond to a voicemail left on Tuesday afternoon. 

State health officials are now offering testing to all the jail’s inmates and staff, Nirav Shah, director of the Maine Center for Disease Control and Prevention, said Tuesday. The state is also investigating what caused the outbreak.
