Former Minneapolis police officer convicted of murdering George Floyd, was stabbed by another inmate and seriously injured Friday, Nov. 24, 2023, at a federal prison in Arizona.

The attack happened at the Federal Correctional Institution, Tucson, a medium-security prison that has been plagued by security lapses and staffing shortages.

The Bureau of Prisons confirmed that an incarcerated person was assaulted at FCI Tucson at around 12:30 p.m. local time Friday. In a statement, the agency said responding employees contained the incident and performed “life-saving measures” before the inmate, who it did not name, was taken to a hospital for further treatment and evaluation.
