(La Porte, IN) - A residential fire on the 1300 block of Federal Avenue in La Porte over the weekend remains under investigation.

Fire Chief Andy Snyder said the fire was in the attic on one side of the duplex. Structure damage was minimal, thanks mainly to the watchful eyes of the neighbor across the street. Nobody was home where the fire occurred.

Part of the ceiling had to be torn down to get water on the flames in the attic's insulation. The home would need repairing before the resident could move back in.

Snyder said the cause is unknown but hopes clues turn up during the ongoing investigation.
