Union representative Al Lewis tells FOX 2 Chuck Randazzo is suspended for 15 days and Sgt. Shawn Kritzer for 30 days.
Lewis adds Randazzo was suspended for excessive force and causing the department disrepute. Kritzer was suspended for improperly administering medical attention to Floyd Dent.
Officer William Melendez was fired last month and charged with assault. He denies any wrongdoing.
Dash cam video shows Melendez pulling the 57-year-old Dent from his car and punching him.
Melendez was in court briefly Tuesday morning. His preliminary exam has been set for the last week of May.
Inkster on Tuesday named Joe Thomas interim police chief. He replaces Vicki Yost, who quit two days after Melendez was charged.
