UPDATE: 4:30 p.m. 11/21/2020-- The Duluth Fire Department is investigating the cause of a structure fire that occurred in the downtown area Saturday morning.
Crews responded to the building adjacent to Wabasha Books on East 1st Street around 9:30 am.
According to the owner of the building, it was an old antique shop that was being used for warehouse space.
Fire Department Officials said they aren't sure what caused the fire.
"Crews have been responding to the fire in a defensive way. What that means is when we have a fire as big as this one, we aren't able to go inside the building. We're mostly trying to just put it out," Kate Van Daele with the City of Duluth said.
The Duluth Fire Marshal's office was on scene canvassing the perimeter.
There are no injuries reported.
