US police are investigating the death of a 21-year-old man who died after he was handcuffed and put into the back of a police car.
Chavis Carter, 21, was riding in a truck on July 28 when the vehicle was stopped by police.
Officers from Jonesboro, Arkansas, discovered that Carter had an outstanding arrest warrant related to a drugs charge, and decided to arrest him.
A police report into the incident revealed that Carter was searched twice, handcuffed and put into the back of a police car.
Shortly afterwards he was discovered inside the car covered in blood.
The police report said Carter had concealed a gun during the two police searches and had then used it to shoot himself in the head.
Carter later died in hospital. The police report lists his cause of death as suicide.
The incident has angered parts of the community in Jonesboro, with some people suggesting that Carter’s death was not a suicide.
Hundreds of people gathered in Jonesboro on Monday for a vigil in memory of Carter, with many in attendance questioning the police account of what happened.
Jonesboro police chief Michael Yates said that the death was "very unusual".
"Specifically, how Carter suffered his apparently self-inflicted gunshot wound remains unexplained and (the) investigation ... continues given the unusual nature of this event," Jonesboro police said in a statement.
