SOUTH SIOUX CITY | South Sioux City Fire Chief Clint Merithew called a chain of grass fires Saturday "suspicious" and could have been done on purpose.
A Thursday press release said the department-- with Dakota City and Homer crews-- responded to three separate vegetation fires Saturday at the Kingsbury Interchange, Highway 20 and U.S. 77 bypass.
The fires were extinguished and the investigation of the cause determined them to be "suspicious in nature with probable cause of incendiary," the release said.
Smoke from grass fires near roadways can reduce visibility for drivers and can be dangerous, the release said.
Anyone with information on the fires should contact the department at (402) 494-7508, the release said.
