(Michigan City, IN) - Michigan City firefighters fought a three-story blaze near the lakefront.

Just before 7 a.m. last Friday morning first responders were called to 305 Beachwalk Lane where a home was engulfed in flames.

The residence was empty at the time. Three firefighters fell through the porch while containing the blaze, but luckily they were not injured. According to a spokesperson for the fire department, it took a couple of hours for crews with three engines and a tower truck to maintiain the fire. They had to return later to deal with hot spots.

The State Fire Marshal brought in a chemical-sniffing dog to detect any possible accelerants that might have been involved. That investigation is ongoing.
