A police officer in the US state of Ohio has shot dead a 16-year-old black girl while responding to an emergency call over an attempted stabbing.
The teenager involved in the incident, in the state capital Columbus, has been identified as Ma’Khia Bryant.
Columbus police have produced bodycam footage which appears to show the girl attacking others with a knife before being shot.
An inquiry is under way, with officials urging local residents to remain calm.
The officer involved has been placed on paid administrative leave.
Police were called to an address in a south-eastern area of Columbus at about 16:45 local time (20:45 GMT) on Tuesday, the Columbus Dispatch newspaper reported.
Bodycam footage provided by the police shows an altercation with a group of individuals outside a house before one of them – said to be Ma’Khia Bryant – appears to lunge at another member of the group with a knife in hand.
A police officer then approaches the group in the driveway and shouts “get down” before firing several shots, fatally injuring the girl.
The officer is heard saying in the footage: “She had a knife, she just went at her.” A bystander shouts that she was just a child.
Officials have said the officer opened fire in order to save the life of one of the girls. A woman, identified in local media as Ms Bryant’s aunt said her niece was simply defending herself after being attacked.
Hazel Bryant was quoted by local TV station WSYX-TV as saying: “She was a good kid. Yeah, she had issues, but that’s OK. She didn’t deserve to die like a dog on the street.”
Speaking to local broadcaster WBNS-TV, Ma’Khia Bryant’s mother, Paula Bryant, said she was “hurt” by what had happened and that her daughter was a “loving girl”.
“This shouldn’t have happened,” she said, adding: “I want answers.”
Paula Bryant said her daughter, who had been staying at a foster home, was “looking forward to coming home”.
At a news conference, the interim chief of Columbus Police, Mike Woods, said an inquiry was being conducted by the Ohio Bureau of Criminal Investigation. -BBC
