At least eight people were killed in a late-night shooting at a FedEx facility in the US city of Indianapolis by a gunman who is believed to have then killed himself, police said.
Multiple others were injured on Apr 15 when gunfire erupted at the facility near Indianapolis International Airport, police spokesperson Genae Cook said.
At least four people were hospitalised, including one person with critical injuries. Another two people were treated and released at the scene, Cook said.
The shooter was not immediately identified and investigators were still in the process of conducting interviews and gathering information.
Cook said it was too early to tell whether the shooter was an employee at the facility.
Police were called to reports of gunfire just after 11pm and officers observed an active shooting scene, Cook said.
