The FBI has agreed to investigate the beating of an African American man by Minneapolis police officers earlier this year. Derryl Jenkins was arrested in February after he was pulled over for speeding. Video of the arrest show a group of officers kicking and punching Jenkins while he was being held face down in the snow. A taser is used at one point during the arrest. Charges have since been dropped against Jenkins, but no disciplinary action has been taken against the officers involved.
