CHICAGO -- Chicago's Office of Emergency Management is investigating a racial slur used on a police radio frequency.
The comments interrupted an exchange between a police officer and a dispatcher sunday morning.
Officials say they believe the comments were made by an "unauthorized user."
Here's a transcription of the audio:
Male voice: "Typical f---in' n-----s."
Officer: Find out what radio that comment came from."
Dispatcher: "You know, we don't get radio numbers, but I'm already holler' for my supervisor."
Male voice: "All black lives matter, man f---in' n-----s."
A police spokesman said issued the following statement:
"The statements made are absolutely unacceptable and Police Interim Superintendent John Escalante has ordered an immediate internal affairs investigation. Should the investigation reveal that a member of the police department made the statements, he will be immediately suspended and disciplinary proceedings will be launched."
