About 46 acres went up in flames Thursday near Vanoss in what Pontotoc County Sheriff's Office officials said may be a case of arson.
Undersheriff Arnold Scott said deputies were actively searching for a suspect they believe intentionally set fire to two sections of grassland about a mile west of County Road 3450 on County Road 1540 near Vanoss.
"That's the report we got," Scott said. "Right now there's supposed to be someone in the area out there starting fires. We don't have a vehicle description, but it was reported (the suspect) was headed back down the county road toward Garvin County."
Scott said anyone who sees something suspicious in the area needs to call 911.
"We need to find out who's doing this," Scott said.
Pontotoc County Emergency Management Director Chad Letellier said both fires were contained and in the "mop up" stage.
"One fire was about 40 acres and the other looks like it was about six or seven acres," Letellier said. "They look like they were both set from the road."
