CAZENOVIA, N.Y. (AP) _ State police say a 10-year-old boy is in critical condition after falling 18 feet into an old well while he was playing hide-and-seek with friends in Cazenovia.

The Post-Standard reports the incident happened Friday when the boy was playing with other kids at a Halloween party.

The boy reportedly climbed onto the cover of the old stone well and broke through the rotted wood, falling into the water below. Emergency responders arrived after several of the children realized what had happened.

The boy was unconscious when he was pulled out by rescuers. His name wasn't released.
