Niagara County Sheriff's deputies were called to the former Summit Park Mall on Sunday morning for a large water break inside the building.
The inside of the now-closed mall was flooded, with water about 4 to 6 inches in places, and was water was pouring out of the mall into the parking lot when deputies arrived about 9 a.m. A property manager said most of the store spaces were flooded.
The property manager said a hatch on the roof above the utility room was opened indicating an unknown suspect possibly made entry. The manager said the last time he checked the utility room was within the last week and did not notice the hatch open.
With the hatch being open for the last few days, three water valves froze and burst.
Wheatfield water Department were notified and responded to shut down the water main.
The manager stated that the three water valves would cost approximately $100,000 to repair.
There appeared to be about $500,000 to $1,000,000 in water damage to the rest of the building.
