Arnolds Park, IOWA (KTIV) -
Investigators are still trying to figure out what caused the fire that destroyed the Mineral City restaurant in Arnolds Park, Iowa.
Arnolds Park-Okoboji Fire Chief Chris Yungbluth says the State Fire Marshal and insurance investigators are continuing their probe.
Thunderstorms with intense lightning had been in the area Sunday evening, a few hours before the fire was reported.
However, investigators aren't saying if that could have been a factor.
No injuries were reported.
