The police have arrested a Sri Lankan national in its probe of a recent explosion at a local oil storage facility, police officials said Monday.
The arrest came one day after an explosion at the oil storage facility in Goyang, just north of Seoul, consumed a large storage tank with 2.66 million liters of gasoline, enough to fill 250 tank trucks.
The police said the 27-year-old Sri Lankan is believed to have accidentally caused the fire by releasing a sky lantern in the vicinity of the oil storage facility.
The police believe the sky lantern may have started the fire when it fell on the lawn of the oil storage facility, causing flames that later spread into the ventilation system of the oil tank, causing the explosion.
The 27-year-old is said to be a construction worker currently working at a site near the facility.
