A cellphone video shows a yacht fire in Norwalk that started because of a grill fire, officials say. 

The boat caught fire Wednesday night near Sunset Grill.

The video was taken by a bystander. 

The fire department says a propane grill at the back of the 80-foot boat caught fire, sending thick smoke billowing into the air.

A police officer dining at the Sunset Grill saw the flames and helped evacuate the vessel.

No one was hurt.
