UPDATE: Crews battle fire at South Bend home

SOUTH BEND, Ind. (WNDU) Investigators are trying to figure out what caused a house fire in South Bend.

Flames broke out at around 9:30 a.m. Thursday at a home on South Michigan Street near East Victoria Street.

We're told paramedics driving by noticed the smoke and called firefighters, but no one was in the home when the fire erupted.

"One of our ambulance companies was driving down the street and saw some smoke, and they investigated and there was smoke coming out of this house," Battalion Chief Mike Lagodney said. "So, we pulled up first. We had the second floor there where you can see that window there on the right. We had heavy brown smoke pushing pretty hard from the second floor and we had visible fire. We sent crews interior to do a search of the first floor. We were told that the building was vacant. We still searched it and searched every room to make sure there was no one in there. No one found, no injuries reported whatsoever, on our end or any civilian end. A lot of water, lot of fire, lot of water."
