DOJ to release report on Chicago police abuses

The Justice Department plans to release a major report on Chicago police after a yearlong civil rights investigation.

Officials will make it public Friday.

The investigation into the 12,000-officer police force began in 2015 after release of a video showing a white officer fatally shooting black teenager Laquan McDonald 16 times.

An official familiar with the report has told The Associated Press the report would find constitutional violations over years. He spoke on condition of anonymity because he wasn't authorized to speak publicly.

Chicago Mayor Rahm Emanuel pushed through reforms since the investigation began, including overhauling a police oversight body. The report's likely to call for more reforms.

Reports in recent years have been followed by reform plans enforced by courts.
