Chief Alfonso Morales said in a statement Friday that one officer was suspended for 15 days, a second was suspended for 10 days and a third for two days. The Milwaukee Journal Sentinel earlier had reported on the suspensions.
Morales also says eight officers will receive a policy review. He says the officers' names will be released after a required legal notice.
Police used a stun gun on Brown when officers detained him for a parking violation in January. Video of Brown's arrest was publicly released Wednesday.
Brown told the Journal Sentinel on Friday that he "gave in" when police used a stun gun on him because he didn't want officers to "pull out their guns.''
