Witnesses to the arrest of George Floyd have given emotional testimony about being at the scene of Mr Floyd's arrest.

The teenager who filmed the viral video from the scene, a city fire-fighter who begged police to check Mr Floyd's pulse, and a nine-year-old girl on a walk to get snacks have all testified that they watched Mr Floyd under the knee of ex-police officer Derek Chauvin.
