At least eight dead in Indianapolis shooting

An Indianapolis police officer said the authorities did not feel there was an active threat to the community anymore.

"Today it is very heartbreaking and, you know, Indianapolis Metro Police Department, the officers responded, they came in, they went in and they did their job," Officer Genae Cook said.

The incident occurred at a FedEx operations center near the Indianapolis International airport, after 11pm local time on Thursday night.

Cook said four people were transported to hospitals, one in critical condition with gunshot injuries and three others with various other injuries.
