CHESTERTON, Ind. (AP) — The National Weather Service says a tornado packing winds up to 120 mph tore the roofs off a school gymnasium and an apartment building in northwestern Indiana.

The weather service says Wednesday night's tornado left a 2 1/2-mile-long path of damage as it cut across the Porter County town of Chesterton about 15 miles east of Gary.

The tornado, which left a five-block-wide path of damage, tore away the Chesterton Middle School gymnasium roof, heavily damaged its glass atrium and left water damage in classrooms.

Town Manager Bernie Doyle says one minor injury was reported as the storm moved through, also damaging several homes and causing power outages.
