The woman, Karen Garner, suffered a dislocated shoulder, fractured arm and sprained wrist after she was slammed to the ground and hogtied during a June 26 arrest, according to a federal lawsuit.
The altercation was captured on police body camera video and shared by Garner's attorney, Sarah Schielke.
Officers Austin Hopp, Tyler Blackett and Daria Jalali were placed on administrative leave over the incident, along with Sgt. Phillip Metzler. Another sergeant, Antolina Hill, was reassigned.
Loveland Police Chief Robert Ticer said at a press conference Friday that Hopp, Blackett and Jalali"are no longer employed" with the department but declined to specify whether they resigned or were terminated.
It's unclear why Metzler and Hill were not among those no longer with the department.
The officers did not immediately respond to NBC News' request for comment.
