Derek Chauvin, the Police officer who is charged with murdering George Floyd, was stabbed in prison, AFP cited the New York Times on Saturday.
The murdering of Floyd sparked various massive across the US that condemned the incident and called for more racial justice.
In 2020, Chauvin knelt on a Black man's neck for more than nine minutes on a Minneapolis street. The dying man started to plead, saying: "I can't breathe."
Those words were the slogan for demonstrators that massively erupted in the US and various cities around the world.
The US Federal Bureau of Prisons confirmed the stabbing incident to AFP.
It said in a statement: "An incarcerated individual was assaulted at the Federal Correctional Institution (FCI) Tucson," in the southwestern state of Arizona.
It added: "Responding employees initiated life-saving measures for one incarcerated individual," the statement said, adding that the wounded individual was sent to a local hospital "for further treatment and evaluation."
The New York Times cited a source that Chauvin survived the attack.
