The Latest on changes within the Chicago Police Department since it came under scrutiny over excessive force allegations and its fraught relationship with the black community (all times local):

The body responsible for investigating complaints against Chicago police is investigating last year's arrest of a Muslim woman whom officers mistakenly identified as a potential terrorist as she walked from a subway station.

A spokeswoman for the Independent Police Review Authority told The Associated Press on Tuesday that Itemid Al-Matar submitted a complaint shortly after the incident. Spokeswoman Mia Sissac declined to provide details.

Al-Matar filed a civil rights suit last week alleging officers singled her out simply because she wore a religious headscarf and veil. It says officers pulled off the garb and later strip-searched her.

A police report says officers had been "on high alert of terrorist activity" on the Fourth of July when they spotted Al-Matar wearing a backpack and exhibiting what it described as "suspicious behavior."

A senior member of the Chicago Police Department who served as interim superintendent during the upheaval over the fatal police shooting of black teenager Laquan McDonald is leaving to become police chief at Northeastern Illinois University.

In a news release Tuesday, the school said First Deputy Superintendent John Escalante will assume the post Sept. 7.

Escalante served as interim superintendent for four months after Mayor Rahm Emanuel fired Escalante's predecessor, Garry McCarthy. That firing came shortly after the release of the video in November, which showed a white officer shooting the 17-year-old McDonald 16 times.

Escalante applied to be the permanent superintendent but the job went to another high-ranking member of the department, Eddie Johnson.

Northeastern Illinois University President Sharon Hahs said in a statement that Escalante "has a national reputation in the field of law enforcement for his experience, integrity and leadership."

Chicago's inspector general has delivered a report on the fatal 2014 police shooting of black teenager Laquan McDonald, a police spokesman confirmed Tuesday.

Spokesman Anthony Guglielmi said the department was reviewing the report and will respond, but didn't know how long the process would take. A spokeswoman for Inspector General Joseph Ferguson refused to comment.

The department also announced the retirement of Deputy Chief David McNaughton, who determined the shooting by officer Jason Van Dyke complied with department policy. That finding was harshly criticized when police dashcam video of the shooting was released in November under a judge's order.

The video contradicted accounts by officers on the scene that the teenager lunged threateningly in their direction. McDonald, who was carrying a knife but walking away from officers, was shot 16 times.

Van Dyke has been charged with first-degree murder. His lawyer says Van Dyke acted properly and resorted to deadly force because he feared for his life.

The department's announcement about McNaughton's retirement makes no mention of the McDonald case.
