An investigation is underway to determine what caused an early morning fire in South Bend Friday.

Firefighters were called to the 2600 block of West Huron Street around 2:30 a.m., where they found a fire emitting from a home that had been converted into apartments.

ABC 57 News reports flames and smoke were coming from the home, and the roof also collapsed while firefighters were attempting to put out the blaze.

No one was injured.
