The number of COVID-19 cases has risen sharply at the Richmond City Justice Center, Sheriff Antionette V. Irving has reported.

The jail reported that as of Wednesday, 91 inmates — 13.5 percent of those being held — have tested positive for the virus and are in quarantine.

That is a reduction from the Aug. 26 report that 103 inmates were in quarantine.

The spike in numbers has sparked renewed protests at the jail from advocates seeking release of nonviolent offenders.

The Richmond Police Department arrested 11 people Tuesday, including a bicyclist who allegedly sought to interfere with the towing of an illegally parked vehicle, six others who allegedly obstructed officers seeking to restore order and four others alleged to have engaged in disorderly conduct.

A video taken at the scene and posted on social media shows the bicyclist being pushed to the ground by a police officer and striking his face on the sidewalk. The bicyclist had bandages on his face in a photo released by the police department.

The good news from the test results from 1,200 inmates who have been in the jail since testing began in July: None of those with positive tests have required hospitalization and most testing positive have no symptoms, Sheriff Irving stated. The report stated that 10 of those testing positive have minor or mild symptoms.

Also, the jail has plenty of empty space in which to quarantine people. Sheriff Irving reported a total of 675 incarcerated people at the jail, meaning 40 percent of the prisoner space is vacant.

The jail was built to house 1,132 men and women, including beds in the medical clinic and in solitary confinement.
