Federal inquiry into North Chicago police beating

The U.S. Justice Department says it's looking into the case of a suspect who died after North Chicago police beat and shocked him with a stun gun.

Randall Samborn, a spokesman for the U.S. attorney's office in Chicago, says the federal inquiry is preliminary and will determine whether a formal investigation is needed.

The Chicago Tribune reports that the Rev. Jesse Jackson condemned Darrin Hanna's treatment in custody and planned a protest march Saturday dubbed the "10,000 Man March."

Hanna died Nov. 13, a week after officers punched and tackled him and used a stun gun during his arrest. His death sparked protests and led to the retirement of the North Chicago police chief.

But Lake County prosecutors said the officers acted "reasonably" and decided not to charge them.
