LIMERICK TWP., Pa. -

Some Kohl's shoppers got an unpleasant surprise in Montgomery County Friday.

They were forced to evacuate after a fire broke out at this store, in the Lakeside Shopping Center in Limerick Township.

The fire was first spotted on a mulch bed in front of the store, then traveled up an exterior wall to the roof.

No injuries were reported.

Investigators say they're looking through surveillance tapes now, in hopes of finding out how the fire started.
