SOUTH BEND. Ind. --- South Bend fire crews battled a house fire in the 1800 block of S. Michigan Street near Calvert Sunday.
The call came in around 4:35 p.m.
Crews arrived to find a man waving from a second-story window. Firefighters used a ladder to help him escape the home, but then the man fled the scene.
Firefighters don't believe the man lived at the home, which they say was vacant.
They asked drivers to avoid the area for 2.5 hours.
Police reopened the block between Calvert and Dayton shortly after 7 p.m.
"It was a wind-driven fire -- lot of wind, lot of [external] openings. Those openings were directing the fire in all sorts of ways," said Batt. Chief Carl Buchanon, South Bend Fire Department.
Crews battled the fire on all three levels.
Buchanon says the fire destroyed power lines in the back, making the blaze more difficult to douse.
