Police shot dead a black teenager in front of his younger sister in a killing that has sparked angry protests in Los Angeles.
Officers from the city’s police department said Carnell Snell Jr was killed after they noticed the car he was travelling in had a paper licence plate and believed the vehicle may have been stolen.
While in pursuit the police claim the 18-year-old got out of the vehicle with another man and started to flee.

Sergeant Barry Montgomery said they chased Mr Snell Jr to the back of a house, where they shot him.
The other man, believed to have been the driver of the car, fled the scene and is currently on the run.
Sgt Montgomery said a gun was removed from the scene, but Mr Snell Jr’s family deny he was armed.
His younger sister, Trenell Snell, said she was sitting with friends outside the house when she saw her brother running from police.
She said she began to run as well and heard gunfire. She dropped to the ground and saw her brother was being handcuffed on the ground.

As news of the shooting spread, protests erupted around the crime scene as the family described Mr Snell Jr as respectful young man who liked skateboarding and loved his family.
One protester at the scene, Tia Gonzalez, 36, told the Los Angeles Times she had come because she knew the community was “going to be hurting”.
She criticised the recent spate of shootings of black men in the US by police, saying: “A police officer should not be the judge, the jury and the executioner”.

It comes after days of protests near San Diego, where police shot a black man who was believed to have been “behaving erratically”.
Meanwhile in Pasadena, California, a black man armed with a knife was shot dead by police, prompting two mostly peaceful protests.
Campaigners, including the Black Lives Matter movement, say police are too cavalier when it comes to pursuing black suspects.
The high-profile deaths of men such as Keith Lamont Scott and Terence Crutcher have prompted calls for prosecutions of the police officers involved.
