Police have shot dead a gunman after he killed three people and injured 14 more in the US state of Kansas.

Ten of the people injured were shot at a lawnmower factory in Hesston, where the gunman had been an employee.

Local media say 38-year-old Cedric Ford started shooting at around 17:00 local time in the town of Newton, where he shot a truck driver in the shoulder and another man in the leg, before stealing his car while driving towards his place of work at Excel Industries.

Once he arrived at the site, he opened fire in the car park, killing one person, before continuing his shooting spree inside the factory where he killed two more people and injuring many more.

Police have said that they do not believe the shootings are terrorism-related.

The attack comes just days after another mass shooting incident in Michigan, with gun control an increasingly hot button topic in the US presidential election, where pro-gun and supporters of gun control are split along party lines.
