CUDAHY, Wis. (CBS 58) – The Cudahy Fire Department responded to a home twice for fires within the last two days.

The department was most recently called to the unoccupied home near S. Swift Ave. and E. Underwood Ave. around 2 a.m. on Wednesday.

Authorities say an investigation is now underway because it is unusual for hot spots to pop up days after an initial fire.

Crews were first called to the home on Monday for a fire. No one was hurt and authorities say the fire was put out quickly.
