Eric Sloan Parker, 26, was charged by the FBI last month with felony civil rights abuse for slamming Sureshbhai Patel to the ground - an incident caught on another officer's dashboard camera. That charge carries up to 10 years in prison.
He is set for arraignment before a federal magistrate in Huntsville, Alabama. Lawyer of Parker says he would plead not guilty.
Parker also faces state assault charges. Hearing for this case is scheduled for May 13.
