CHICAGO - The Latest on the release of videos and other materials by the Chicago agency that investigates police misconduct (all times local):

11:50 a.m.

Chicago Mayor Rahm Emanuel says there's "a lot more work to do" on transparency as the city publicly released information about 100 cases of alleged police misconduct.

Emanuel said in a statement that releasing the videos Friday morning was an "important next step" in the city's efforts to be more transparent with police issues. The Independent Police Review Authority released videos, audio recordings, police reports and other materials.

All the cases involve shootings by officers, use of stun guns resulting in great bodily injury or death, or in-custody incidents where there was great bodily injury or death.

Emanuel says releasing the videos and other materials changes the decades-old city practice of waiting to release evidence until investigations are concluded. The mayor says the city will continue to work toward reform in the months ahead.

The chief administrator of the agency that reviews Chicago police misconduct says publicly releasing information about 100 cases is "an important first step" toward rebuilding trust in police.

The Independent Police Review Authority released videos, audio recordings, police reports and other materials on Friday.

Chief Administrator Sharon Fairley told reporters Friday that it's clear the city has struggled with questions about policing and police accountability and releasing the information helps increase transparency.

She says the release of the video isn't a gauge of an investigation into an officer's behaviour. She also cautions that the videos only tell part of the story and don't have the wider context.

The Chicago agency that investigates police misconduct cases has released more than 300 video clips from 101 incidents it has investigated, along with recordings of 911 calls and original police reports.

The Independent Police Review Authority posted the material to its website Friday. All the cases involve shootings by officers, use of stun guns resulting in great bodily injury or death, and in-custody incidents where there was great bodily injury or death.

It's the latest step in the city's effort to regain public trust in its beleaguered police force.

The video was captured by police dashcams and body cameras as well as bystanders recording on cellphones.

One video shows an officer slamming a woman face-first into the hood of a car during a party in a West Side neighbourhood in July 2014. The city recently agreed to pay the woman $50,000 in a settlement.

Another shows the aftermath of a police shooting that injured a man accused of beating someone with a baseball bat

The head of the Chicago police union says its members oppose the release of videos and other materials from police misconduct investigations because they don't tell the whole story of what occurred.

Dean Angelo is president of the Fraternal Order of Police, Chicago Lodge #7. He says some incidents occurred up to five years ago, and in some cases the officers involved still haven't been interviewed by investigators.

He says some of the videos are only partial clips of what happened, and don't include audio.

The agency that investigates Chicago police misconduct cases is releasing materials from about 100 incidents on Friday. It's part of the city's efforts to regain the public's trust in police.

Angelo says the agency is trying to deflect attention from the poor job it does investigating cases.

The Chicago agency that investigates police misconduct cases plans to release videos, audio recordings and other material from about 100 incidents. It's the latest move in the city's effort to regain public trust in its beleaguered police force.

Releasing records related to open investigations is nearly unprecedented for a police department that for decades had a reputation for secrecy. Officials waited until November, following a judge's order, to make public video from more than a year earlier showing a white police officer fatally shooting a black 17-year-old.

The Independent Police Review Authority wouldn't say which cases would be included in the batch of material. There was no indication any footage would be as explosive as the October 2014 dashcam video showing the death of Laquan McDonald, who was shot 16 times.
