The FBI has agreed to investigate the beating of a man by Minneapolis police officers, after a video of the incident was released.
Derryl M. Jenkins was arrested in February 2009 during a traffic stop, and charged with assault and refusing to submit to alcohol tests.
The charges were later dropped but police chief Tim Dolan has admitted that some of the responding officers' actions are cause for concern.
A video of the incident has since been released on the request of Jenkins.
It shows several officers arrive at the scene after one policeman tried to make the initial arrest. Many of the backup officers are seen punching and kicking Jenkins as they try to handcuff him.
