(BBC News) Minneapolis ex-police officer Derek Chauvin, convicted in the murder of George Floyd, has been stabbed at an Arizona prison, U.S. media reports say.
A source told AP the 47-year-old was seriously injured by another inmate.
The New York Times, citing two people with knowledge of the situation, also reported that he was attacked.
Chauvin, who is white, is serving multiple sentences for the black man’s death, which triggered huge protests against police brutality and racism.
The Bureau of Prisons confirmed in a statement that an inmate at a federal prison in the city of Tucson was stabbed at 12:30 local time (19:30 GMT) on Friday.
The agency said employees contained the incident, and “life-saving measures” were performed on the inmate, who was then taken to hospital. The name of the prisoner was not given.
Nobody else is thought to have been injured, and Chauvin is reported to have survived the attack.
