PHOENIXVILLE, Pa. -

Officials say a fire that displaced more than a dozen people in Chester County appears to be accidental.

The fire broke out Sunday at an apartment building on Church and Bridge Streets in Phoenixville.

No one was hurt, but more than a dozen people, including at least ten children, were displaced.

The Chester County Fire Marshal says crews found smoking materials on a bed in the top unit and that's where they think the fire started.
