A police dashcam video showing the arrest of a woman who died three days later in custody has been released by officials in Texas.
The coroner said Sandra Bland hanged herself in her cell but her family have called for an independent autopsy.
Footage of the 10 July arrest, released by the Texas Department of Public Safety, shows Sandra Bland's car being pulled over for failing to signal and then an ensuing confrontation with the officer.
