NIAGARA FALLS, NY — Repairing potholes took a unique turn in the Cataract City on Thursday.

While the city's "Pothole Killer" was patching some holes, the vehicle met a pothole-turned-sinkhole near 18th and South streets, causing the vehicle to go through the road's surface.

The Niagara Falls Water Board is on site assessing what it calls "a potential water main break."

It happened at about 4 p.m. Thursday.

No injuries were reported.
