Fatal Chicago shooting spree

At least one person is dead and four police officers are injured after a gunman opened fire in deadly shooting spree at a business in suburban Chicago.

City spokesman Clayton Muhammad said the suspect - believed to be an employee of the business - had been "neutralised" after the incident at the Henry Pratt Co. building.

The wounded police officers were said to be in a stable condition. The town of Aurora, Illinois, is about 65 kilometres west of Chicago.

An employee at the Illinois company where the shooting occurred claimed the gunman was a co-worker.

John Probst told ABC7 that he ran out of the back door of the Henry Pratt Co. building in Aurora as the shooting unfolded on Friday afternoon local-time.

Probst said he recognised the gunman and that he worked at the company.

He said the gunman has "a pistol with a laser" and a colleague was "bleeding pretty bad".

"One of the guys was up in the office, he said this person was shootin', and, he come running down and he was bleeding pretty bad, and the next thing you know he was walking back and forth, I heard more shots, and we just left the building," Probst said, according to the local news site.
