Antonio Smith accuses Valdosta, Georgia, and its police department of using excessive force when they wrongfully arrested him.
Police crews had been sent to a Walgreens with an arrest warrant for an African-American man wearing a brown hooded sweatshirt and blue trousers, who had been harassing customers.
While one officer was collecting information about Mr Smith, who had been near the pharmacy, another officer arrived and told him to put his hands behind his back, believing he was the subject wanted by the warrant.
When Mr Smith pleaded his innocence, he was brought down to the ground in a police control technique, which injured his wrist.
He is suing for $700,000 (£563,626) in damages.
