BALTIMORE (WJZ) — Baltimore City Firefighters remained on the scene of a four-alarm fire at an old warehouse Friday morning. The blaze itself broke out Thursday night.

The fire broke out just north of Old Town Mall, south of central booking and west of Dubar High School’s football field.

A number of roads downtown by the JFX are closed Friday morning as crews attempt to put out remaining hot spots.

“It’s a fairly large warehouse, it’s about a block long and a half a block wide,” Blair Adams of Baltimore City Fire Department said. “It’s two sides, one side was inoperable and the other side of the warehouse was functional.”

There were mattresses inside from a business, but about half of the building was vacant.
