SIOUX FALLS, SD
Authorities in Sioux Falls are investigating another case of arson this week.
Police spokesman Sam Clemens says a fire inside an unattached garage Wednesday afternoon was deliberately set.
Clemens says authorities don't yet know if the fire is connected to three others late Monday and early Tuesday. Those fires damaged a garage, a shed, a Dumpster and a utility trailer.
Police have no suspects in any of the fires.
