McKeesport police today warned consumers that a shipment of 1,000 gallons of gasoline was mistakenly placed into a kerosene storage tank this month at a service station in that city.

The mistake occurred at Gas USA at Lysle Boulevard and Walnut Street.

At least 35 gallons of gas was sold to consumers who believed it to be kerosene.

Those consumers should return the fuel to Gas USA.

Police said there is a risk of fire or explosion if the gasoline is used in a heating device.
