FLINT, Mich. (AP) - Authorities say firefighters in Flint responded to five fires at vacant buildings during 4-hour span over the weekend.
The Flint Journal reports the fires on the city's east side were reported Saturday night. Other area departments assisted in extinguishing the blazes.
Two fires were at commercial structures and three were at residential buildings. One person was injured in a fire that destroyed a home that may have been occupied by squatters.
Fires at vacant buildings have been a significant problem for Flint that has strained its firefighters. On July 4-5, crews responded to eight suspected arsons at abandoned homes. A string of possible arsons in an eastside Flint neighborhood also was reported in June.
A string of fires July 1 led to charges against a number of people.
