Chicago police have launched an investigation to determine how information related to the investigation of an alleged attack against "Empire" actor Jussie Smollett was leaked to the media.

A spokesman for the city's police department told ABC News late Thursday that an investigation into the leaks had launched in February after some of the information leaked to the media about the case from law enforcement sources proved to be inaccurate.

"I will also add that there were several agencies briefed with information during that time and some of the information that went out was not factually accurate," Chicago Police Department's Anthony Guglielmi told ABC News. "These types of investigations are fairly common so that we can determine if we have any integrity issues for future cases."

Guglielmi added to ABC that the probe was launched "during the interrogation of the brothers when information leaked out" concerning two men who allegedly knew Smollett and who police now say were hired by the "Empire" star to stage an attack.

Smollett told police earlier this year that two men shouting racist and homophobic slurs as well as pro-Trump messages such as "This is MAGA country" attacked him late at night while he was walking in a Chicago neighborhood, dousing him with an unknown chemical substance and placing a noose around his neck.

Police investigated the claim initially as a hate crime, but later told reporters that they did not think Smollett's story was true.

The actor has maintained his innocence but has been largely written out of the hit show on which he once had a starring role.

Smollett was charged with one count of felony disorderly conduct over the alleged false report and is awaiting trial.
