A man who was among the onlookers shouting at a Minneapolis police officer to get off George Floyd last May has told a court he called 911 after paramedics took Mr Floyd away, “because I believed I witnessed a murder”.

Donald Williams, a former wrestler who said he was trained in mixed martial arts, including chokeholds, returned to the witness box a day after describing seeing Mr Floyd struggle for air and his eyes roll back into his head.
