HARTFORD, Conn. (WTNH) – Hartford firefighters said they battled an aggressive blaze at Sigourney Market on Ashley Street near Huntington Street on the Fourth of July.

The fire broke out around 3 a.m. on Monday morning, and officials reported that people had heard explosions coming from the building just before crews arrived.

One neighbor even said he smelled smoke in the area before the market caught fire, but thought it could have been fireworks.

“At 4:30 my wife calls me [to say that] she’s on her way to work, comes out of our apartment, and says the market is on fire. When I came down the whole place is burning,” said the neighbor. “To be honest, I just moved here a couple of months ago, but this is a great loss to the community.”

Upon arriving at the market, firefighters saw smoke coming through the windows.

The Assistant Fire Chief on the scene stated to press that this was a second alarm fire, and there was heavy smoke surrounding the building. Though the metal roof made fighting the fire more difficult, he said, the flames have since been put out.

According to officials on the scene, no one was displaced from the property due to the flames.

Two firefighters were taken to St. Francis Hospital at this time for minor injuries. No other injuries have been reported, and fire officials stated the second floor of the building was vacant when the fire started.

Investigators classified the cause of the fire as undetermined as there was too much damage from the blaze.

The structure was deemed unsafe due to the roof collapsing. Fire officials said the building had to be torn down.

The fire is currently being investigated by the Fire Marshal’s Office, said city officials.
