Derek Chauvin stabbed in prison - US media reports

Minneapolis ex-police officer Derek Chauvin, convicted in the murder of George Floyd, has been stabbed at an Arizona prison, US 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.
