NILES, Mich. -- Crews are investigating a number of small fires set at the Walmart in Niles.  Officials tell us the fires were set intentionally.

It happened at the Walmart in the 2000 block of South 11th Street.  The call came in just before 1:45 a.m. Thursday.

We're told several small fires were set in the clothing areas of the store.  Employees put most of them out before firefighters got to the scene.

Investigators did not say who started the fires, or why they did it. 

A fire was extinguished at the Walmart, in the clothing department, on South 11th Street earlier this year, on April 26.
