WalMart reopened

is store in Newnan Wednesday after a suspicious early Tuesday morning

fire shut down the giant retailer for a day.

Newnan Fire

Marshall Ricky Ayers said the Newnan Fire Department responded to the

fire on Ga. Highway 34 at approximately 8:12 a.m. Tuesday.

"The fire

was contained in the domestic section, and the store's sprinkler system

had gone off," he said.

Newnan firefighters,

along with help from Coweta County, had the fire extinguished quickly,

but the store could not reopen Tuesday because of extensive water damage

and smoke, Ayers said.

Ayers said

the department is investigating the incident as a possible arson.

"We think

the fire was set to cover up another criminal activity, like shoplifting,"

he said.

The state Fire

Marshal Office and Insurance office are offering up to a $10,000 reward

for information in the case, he added.
