Dallas Fire-Rescue responded to the fire in the 2500 block of Evelyn Street around 10 p.m. Firefighters found debris — such as windows, bricks and burglar bars — that “appeared to have been blown from the one-story home” when they arrived, the department said. Six people were inside the home when it caught fire.

The department said one 911 caller said something “just blew up.”

Firefighters extinguished a fire inside a bathroom coming from underneath a bathtub. They said an exterior wall had been blown off.

The department said one person was in the bathroom at the time of the fire. Paramedics found that person standing in the street outside the home when they arrived and took them to a hospital for treatment. The department did not disclose their injuries or the person’s condition. No one else was hurt, but the house incurred significant structural damage.

As of 8:45 a.m. Saturday, the department said the investigation is ongoing, but investigators believe the fire was accidental and started in the bathroom from a gas explosion.
