Chicago police underreported crimes, audit shows

The Chicago inspector general has found that the city's police department underreported aggravated assault and battery crimes in 2012.

The city's Office of Inspector General released a report on Monday detailing Chicago Police Department's crime statistics reporting in 2012. It found that the department failed to count each victim in multiple-victim incidents, resulting in a 24 percent undercount. Those police reports go to the Illinois Uniform Crime Reporting Program, which feeds information to the FBI. The inspector general called them "significant errors."

The inspector general said that Chicago police officials agreed with its findings. The inspector general said the department is reviewing all aggravated assault and batteries from 2012 and 2013 to ensure accurate statistics are reported.

Inspector General Joe Ferguson said he found the police department's response "robust" and "encouraging."
