DETROIT, MI - Melvindale Police are going door-to-door in a neighborhood near the site of an apparent explosion at the Marathon Detroit Refinery,

according to XXYZ 7 Action News.

The refinery's firefighters were streaming water on to an area of the complex where black smoke was billowing from the building on Saturday evening.

Marathon spokesman Shane Pochard told the Detroit Free Press the fire is located in one of the refinery's smaller tanks.

The refinery borders Melvindale, though the Melvindale fire department reportedly has not been asked to respond.

Police are re-routing traffic in the area. Two exits on Interstate 75 next to the refinery have been closed off by police.
