Chicago police say outsiders behind slurs on radio traffic

CHICAGO (AP) - Authorities say the recent transmission of racial slurs over the Chicago police radio frequency came from "external, unauthorized radios."

While a police dispatcher and an officer were speaking on March 13, someone interrupted with profanity and a racial slur.

Authorities say another racially offensive remark was broadcast Sunday.

Police spokesman Frank Giancamelli in a statement Monday called the racial comments "abhorrent and absolutely unacceptable." He added there is no evidence the speaker is a city employee, however, the Office of Emergency Management and Communications and the police department continue to investigate.

Authorities say racially offensive remarks were broadcast Sunday over Chicago police radio.

Although police frequencies are legally restricted to official traffic, Chicago police and OEMC officials say they've had to deal with people, including security guards, making unauthorized transmissions.
