Former Minneapolis police officer convicted last month of the murder of the black man George Floyd has requested a new trial.
Derek Chauvin’s legal team have filed court documents alleging misconduct by both prosecutors and jurors.
Chauvin, who was captured on video kneeling on Mr Floyd’s neck for more than nine minutes, was found guilty of murder and manslaughter.
His lawyer says his client was deprived of a fair trial.
The rare verdict against a police officer was considered a milestone in the racial history of the US and was widely applauded by Americans. Chauvin faces up to 40 years in prison.
He will be sentenced next month.
