NORTH PLATTE - North Platte Police are investigating a Friday night mobile home fire after Fire Marshal George Lewis called it arson.

KNOP News 2 reports people living in the home told police someone threw an explosive at the home just after 11 p.m.

North Platte Fire Marshal George Lewis says the fire started outside the home at the Patriot Mobile Home Park.

Lewis says steel skirting on the building prevented the fire from spreading.

Lewis says neighbors started putting out the fire with a garden hose before fire crews arrived.
