Dodge County dispatchers received multiple reports of a structure fire on 108 Lakecrest Drive at about 6:20 p.m., according to a news release. The residence was a two-story apartment building with 16 units. Police first arrived to help evacuate tenants and prevent anyone from re-entering. Firefighters deployed three hose lines after officials found flames coming from a second story window.

The cause of the fire is still under investigation, and a damage estimate is unavailable as of Thursday night.
