3 Arkansas troopers suspended after video of assault

Three Arkansas officers are suspended after video shows them beating a man. They were responding to a report of a man making threats in Mulberry, Arkansas. 

Video shows one officer punching the suspect, another hitting him with his knee and a third holding him on the ground 

The Justice Department has opened a civil rights investigation into the incident

Two sheriff's deputies and one Mulberry police officer have been suspended. 

The three officers involved appear to be white, as does the suspect, 26-year-old John Worcester 

His father declined to comment when contacted by The Associated Press 

The attorney for the two deputies said Monday that Worcester attacked one of the deputies, giving him a concussion.
