Officials have released audio of a 911 call and bodycam footage which shows the fatal police shooting of 16-year-old Ma’Khia Bryant.
In the footage, the teenager appeared to be holding a knife as she pinned another woman against a car before multiple gunshots were fired by Officer Nicholas Reardon.
On the 911 call, a woman urged the phone operator to bring police to the property in Columbus, Ohio.
“We need a police officer here now,” a woman can be heard on the call.
“We got these grown girls over here trying to fight us, trying to stab us.
“We need a police officer here now.”
Officers attempted “life-saving measures” after the shooting and Ma’Khia was taken to a hospital where she was pronounced dead.
Ma’Khia’s mother Paula Bryant told US media the teenager had called the police for “protection”.
Officials said the Ohio Bureau of Criminal Investigation would lead an independent probe into the incident.
