The Los Angeles district attorney has filed manslaughter charges against a former sheriff's deputy who fatally shot an unarmed man in 2019, an extremely rare prosecution for an on-duty officer killing in the US.

Andrew Lyons, 37, is facing charges of voluntary manslaughter and two counts of assault with a semiautomatic firearm for the 6 June 2019 killing of Ryan Twyman, in Willowbrook in south LA, the district attorney's office announced on Thursday.
